see im ok with hand 3 if your pretty sure he'll DB with a missed draw. otherwise i agree with massimo that your raise is too small because your not folding out anything thats vbetting the river. plus the only thing your really repping is 78 which makes no sense because you would cbet flop with 78.

for the people who liked hand one i just wanna say that his flop 3-bet minraise is a very fishy bet and people who make these kinds of bets arnt capable of making "correct" laydowns so you lose way too much FE becuase of opp. although you did say you had a read so it might be good for this situation.
