hand 1 - AKs pre is cool. Flop c=bet size is pretty damn bad. Turn is bet-fold
hand 2 - 99. I don't like flop. You can bet-fold or check-fold. Check-fold is better. I mean, you haven't got a turn plan when you check-call. Even if 9d turns you're unhappy, all diamonds mess with your head, all cards T+, etc.
hand 3 - KJo pre is ok, so is folding though. Flop call confuses me, same with turn sizing. Call river.
