Johnathan,
I see this will be a battle of wills. My quoted comments in red. My response in blue.
Let's start from the beginning and just so you know, I no longer subscribe to the beliefs of Jehovah's Witnesses and I do not use their New World Translation of the Bible.

I said: "each one is believed to be God but they are lumped together as one single God."
You said: "Not really lumped together. One God Almighty, YHWH, with a triune nature."
I said: "There is only one almighty God who is the Father"
You said: "Trinitarians agree. And that Almighty God is YHWH"
I said: "The mighty god being his son Jesus"
You said: "This is a false teaching, and mischaracterizes the Trinity. Jesus is the Mighty God, as it says in Isaiah 9:6, but that God is YHWH and not some little "a god,", as it says in the next two words: the child born to us is Mighty God, "Eternal Father." That is but one of many reasons. Immanent trinity, the nature of God in himself before creation, does not include Jesus who was not yet born. Jesus is God-Man, God the Son. And because the Word is eternal, he could not be created."
And this is where it gets tricky, for you. You said, "Immanent trinity, the nature of God in himself before creation, does not include Jesus who was not yet born," and then you say, "Jesus is God-Man, God the Son. And because the Word is eternal, he could not be created."
You have tripped yourself up here. If Jesus was not yet born, how could God have been triune in nature. And after Jesus was born, this adds a 4th person to the "triune" making a "quadrune"
You're basically telling me that Yahweh has a split personality because this is the only way a Triune God could work. And, even if this was the case, it would still mean two individual personalities, not a whole.
Consider John 8:58: ""I tell you the truth," Jesus answered, "before Abraham was born, I am!"
You said that "Immanent trinity, the nature of God in himself before creation, does not include Jesus who was not yet born"
So tell me Johnathan, who was Jesus referring to when he said this to the Jews? Or are you going to tell me this is just another part of Yahweh?
I said: "[the mighty god being his son Jesus], who was God's first creation"
You said: "This is arianism, and another false teaching. The Word was not created, and the evidence is overwhelming."
I have not seen overwhelming evidence of any kind, but for those who aren't aware, here is the defintion of what I am being accused of...
The Arian concept of Christ is that the Son of God did not always exist, but was created by—and is therefore distinct from—God the Father.
I'm afraid that Arius did not invent this concept, the Bible had it first. Colossians 1:15: "The Son is the image of the invisible God, the firstborn over all creation."
I submit to you it would be impossible for Jesus to have always existed, because how could a Father and Son exist at the same time?
Are you saying that Proverbs 8:23-31 is wrong?
"The LORD made me at the beginning of His creation, before His works of long ago. I was formed before ancient times, from the beginning, before the earth began. I was brought forth when there were no watery depths and no springs filled with water. I was brought forth before the mountains and hills were established, before He made the land, the fields, or the first soil on earth. I was there when He established the heavens, when He laid out the horizon on the surface of the ocean, when He placed the skies above, when the fountains of the ocean gushed forth, when He set a limit for the sea so that the waters would not violate His command, when He laid out the foundations of the earth. I was a skilled craftsman beside Him. I was His delight every day, always rejoicing before Him. I was rejoicing in His inhabited world, delighting in the human race."
This scripture clearly indicates that Christ acknowledged his maker. What more evidence is there to prove that Jesus (the man) had a prehuman existence. Even if you do not accept that Jesus (the man) and Christ (the Son of God) are the same, this scipture proves that Yahweh created the son...or whom do you suppose this to be?
Your points about JWs insertion of the word "other" is moot because I do not subscribe to their belief system or their translation of the Bible.
You said: "However, if, as the Jehovah's Witnesses falsely teach, the preexistent Christ is a created creature only, then the Holy Spirit must also have been created and accordingly there would have been a time when there was no Holy Spirit and therefore God would have lacked power and authority and would not have been omnipotent, according to their theory. But, since the Holy Spirit is eternal, which the Jehovah's Witnesses must concede, and the Spirit of God is the Spirit of Christ, and this Spirit is the Holy Spirit, Christ the Word must be eternal."
I have no idea what you are talking about. JWs never said the Holy Spirit was created, they have always taught it was God's Active Force, something God has as part of his existence. JWs never said there was never a time before the Holy Spirit was created. You are confusing the issue. I see this as a straw man argument.
The Scriptures do not say they are equal, coeternal or one single God. Matthew 28:19 "Go, therefore, and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit," This simply shows they are in unity with each other and does not say that they are all one in the same.
Mark 12:28-30 "One of the scribes approached. When he heard them debating and saw that Jesus answered them well, he asked Him, "Which commandment is the most important of all? "This is the most important," Jesus answered: Listen, Israel! The Lord our God, The Lord is One. Love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength."
Jesus was talking about his Father, not a triune god.
Just as the Word (who was also a God in Yahweh's eyes) had taken Eve from the body of Adam to create her, God had directly created the Word from Himself. And since the Word was created directly from God, it can be said that God also created all things, because the Word is an extension of God, as so are we in unified creation. The creation as a whole is unified as helping and serving one another. Remember the Scripture that says to be great you must be a servant of others. It was The Word (God’s Spokesman), who later became Jesus Christ.
Proverbs 8:30 “I was a skilled craftsman beside Him. I was His delight every day, always rejoicing before Him."
John 17:5 Now, Father, glorify me in Your presence with that glory I had with You before the world existed. “Before the world existed”. The Word was with God before the world existed. The following scripture also shows how Jesus existed as The Word before all else.
John 14:28 You have heard Me tell you, ‘I am going away and I am coming to you.’ If you loved Me, you would have rejoiced that I am going to the Father, because the Father is greater than I.
Christ was first The Word and then he became Jesus Christ.
Paul speaks of truly coming to know who Christ was in the following scriptures:
Philippians 3:7-8 But everything that was a gain to me, I have considered to be a loss because of Christ. More than that, I also consider everything to be a loss in view of the surpassing value of knowing Christ Jesus my Lord. Because of Him I have suffered the loss of all things and consider them filth, so that I may gain Christ.
1 Corinthians 11:3 But I want you to know that Christ is the head of every man, and the man is the head of the woman, and God is the head of Christ.
1 Corinthians 15:28 And when everything is subject to Him, then the Son Himself will also be subject to Him who subjected everything to Him, so that God may be all in all.
John 5:19 Then Jesus replied, “I assure you: The Son is not able to do anything on His own, but only what He sees the Father doing. For whatever the Father does, the Son also does these things in the same way.
God is the Creator of spirit energy. The Word was first created as a spirit.
Hebrews 1:7 "And about the angels He says: He makes His angels winds, and His servants a fiery flame;" That reveals they are of powerful design other than flesh.
Luke 24:39 "Look at My hands and My feet, that it is I Myself! Touch Me and see, because a ghost does not have flesh and bones as you can see I have."
Spirit energy does not possess flesh. God started off the Word as a spirit. The rest of creation was created by the Word. This is what the Word is all about. It's what eludes people that lack insight. It is also part of what Christ is to be honored concerning his sacrifice. This is the reason why the Trinitarian belief is a false teaching in God's eyes.
