Blind defense or spewing?

Hand 1. looks good to me. It's always hard to determin if a player is on a steal raise or not.
Hand 2. On flop I think it's good. If capped fold on turn.
Hand 3. No! I don't think it's good to raise this OOP. I would fold the river. He is trying to represent queens but I don't buy it (but if he has them you are still beaten). He probably has something like pair OR the flush and he was on check/call line.
