Given reads, I'd shove turn hand one as we have plenty of fold equity and there's no a lot he'll expect us to carry on betting over two streets for value.
Hand 2 sizing is horrible, also reload pre. I'd go big at $1 or so and shove turns.
Hand 3 is pretty ugly but I'd probably just bet 60c, fold to raise.
Hand 4 I call and call him down.
