In hand 1, obv I don't know how good your opponent is but your line just turns your hand face up. The half-pot bet on the flop and then almost full pot on turn and overbet shove on river is telling me that you were just trying to keep me in on the flop and scrambled to get the money in on the turn and river.

Hand 2, I like betting the turn contrary to what others say it's a decent card to barrel and checking back dooms us to not being able to bet many missed rivers against good opponents. On the river, just check, he's not folding anything after the 2 hits that has you beat except maybe like 44/55 and you're good against any missed bare draws. EDIT: Thought we bet flop and opp called, disregard this analysis. Betting river seems much better now

Hand 3, I probably play it the same, depending on what kind of fish the BB is I might just fold pre
