Hi.

First off, please don't post multiple hands in one post. You'll get a much better discussion if you post them individually.

1) This one is tough, but I think it's a fold. You only beat a bluff and since we're readless I'd think an average villain isn't bluffing enough for a river call.

2) Do not raise the flop. You are either way ahead to a J or way behind an ace, which villain never folds, and a free card isn't worth it. Very rarely is this a flushdraw. Just call the flop. If he bets again on the turn then I'm tempted to fold, but it's probably a call at low stakes. River is a clear check behind since anything he had that you beat now beats you.

3) Nice hand. Preflop is standard. flop is a bet/call. You're probably behind on the turn, but you have many outs (though a diamond is a dirty out). River is a clear fold.
