I got through the battlefield, but I think two or three of the questions are a bit dubious.
For example - although I don't think that God must necessarily be omnipotent, I also don't think belief in an omnipotent god is inconsistent with thinking that 'God could not create a square circle'. Because 'a square circle' is just a trick of human language. It's not a 'very hard thing to make' that god has failed to do. It's just a nonsensical phrase without any referent.
