The scriptures I cited provide more than enough evidence to answer your questions. Why did you not comment on any of them?
I did not comment because I wanted to give you a chance to explain your reasoning. The Scriptures you cited did not answer any of the questions I asked you and I am not surprised you are not willing to answer them yourself. I knew you would not be willing to do so!

The bible says that death happens when a person's soul leaves their body.
What you are referring to as 'soul leaving the body' is a person dying taking their last breath of life. But you are correct, at that point when that occurs is when a person dies. They are then dead, that's death. They do not 'think, feel, remember, talk etc.' at that point. If they could do any of that then they would not be dead, they would still be alive, the opposite of dead. Ecclesiastes 9:5,6
The Scripture you cited about Rachel (Gen. 35:18,19) shows that she was in the process of dying and with her 'last breath' she called out the name, then she died.
Up until she died, she could 'think, feel, remember, talk etc.', after she died, she could do none of that.
The Scripture you cited about the girl (Luke 8:50) likewise shows that she had died/stop breathing but Jesus healed/saved her causing her to breathe again, be alive. When she was dead/not breathing, not able to 'think, feel, remember, talk etc.', her parents were weeping and mourning for her.
Is Jorge in heaven right now and able to 'think, feel, remember, talk etc.'?
Is every pope since Peter all in heaven right now and all able to 'think, feel, remember, talk etc.'?
