Hand one looks good until the river. That's not a scare card ; bet the river.

In hand 2, I would have either bet the turn, or check-raised the turn. EDIT: with 3 opponents, I think check-raising is better. You maybe could even check-call the flop, then check-raise the turn. A check-raise on the turn will be a lot more effective than on the flop, in terms of protecting your hand. It's also nice when people think you've been slowplaying the flush and fold a better hand (if someone folds a small heart on the turn, that's good for you too. If a heart falls on the river, and you get heads up with CO or MP1, you can bet and fold to a raise).
