Question #1: No, there is no way to get away from AA on this flop.
Question #2: I would go all in.
Question #3: Easy call. You're getting over 4:1 in a spot where you will often be a big favorite over a smaller overpair/9/draw.
Question #4: His call is borderline I think. I would make it if I thought either of the players in the pot were bad.

No one is getting away from this hand postflop. Your mistake was not raising enough preflop.
