The only reason I can see to fold the AA would be if the next blinds would take out the other short stack on his next go but he can go round at least 3 more times. You have to play AA here and all in is the preferable move.
Q2
KK QQ JJ I'd be all in. TT I be all in but not be happy! anything lower (PP) I'd still probably go all in as its a turbo and vs the relative stack sizes I feel Id need to move. AK AQ I would go for it. AJ same again but not be happy.
So I'd go in with any PP, AK, AQ, AJ.
and fold everything else, let the other short stack make a decision. I'd never flat call with any of these hands in the situation you stated (though the AA might have been worth a flat call....) Not sure about when it becomes -EV but I'm sure some bright spark will number crunch it for us

But I'm not going to get on my high horse and say my way is right! It's just how I would play the turbo with a low stack.
