Hand 2 and 3: clear value-bets IMO.
Hand 1 is a little confusing though because the river card should look scary to villain, but he doesnt seem to care much.
But Im tending to a reraise here because I cannot imagine which holding he would be raising PF which beats you. He probably has the queen. That means he cannot have a better flush.
He might have a FH. But I think trip Qs is about equally likely.
