It would appear that the name of the god also identifies the name of the Amorite city. The NWT translates this god Shaddai as also being Jehovah. So here we go, rolling all these gods into one.
Shaddai is still one of the Jewish names for God. It's been awhile since Hebrew school but I seem to recall at least 77 names being discussed. I can pray to El, Adonai, Shaddai, Hashem, etc. All the names have different meanings relating to God who is unknowable (except through his attributes) and who is all things (the Lord is One). The name I use depends upon my intent.
If you are interested, here is a glossary of the many names of God.
