No info about our hero or the opp, but here is my general reply.

Hand:
1) b/c and shove as played, just make sure that your 3bet range isnt only AA/KK. Many will ignore all odds if they smell a stacking.

2) I would 3bet pre aswell as played call, as it's a blinds war I dont mind the check behind on the turn if you think he will jump on the river, with that in mind I cant fold now. The bet size at the river is strange, it looks like one of those compensation bets for checking the turn but without any info I cant realy tell.

3) You got a monster, but as it's a utg raise, he is betting vs 4 callers and you got 2 to act behind you, I think calling is fine. Also you have him on a very narrow range later on and with that in mind, when he bet 22$ into you, raise! It looks like a big hand, set/AK/AA with the Ah your pick and here you got him big time. There are so many bad river cards for you that even if you dont end up behind is going to kill your action. If you think he is going to fold his (ex AAh) on the turn why wouldnt he be able to do that on the river aswell? Atleast on the turn he has outs.
