Hand 1 :
Think you can fold PF. You aren't getting the odds to set mine against the raiser, and there's no guarantee the button will call.
Once you get to the flop, it's obv a cooler.
Hand 2 :
Don't think you did anything wrong. C-betting these spots with AK often means you fold out all worse hands, and get action from better (may fold out small pairs), so it's ok sometimes, in position, to check and play a smaller pot.
Hand 3 :
Squeezing these spots with AQ is fine, and once you hit top pair, good kicker, it would be a mistake to fold given the size of the pot versus the your stack.
