You don't have reads and you're making hero calls?

1) I'm raising flop to 12 and checking turn if he calls and I don't improve. Why is op leading three streets with air? The way you played, fold river. He has a pp a lot here.

2) Ditto for hand two. I don't mind the call on flop but who triple barrels on air? Worse, who triple cold calls with absolutely no read against a lot of strength? Granted, marginal hands usually slow down and he's on full blast, but I still hate the calls.

3) This is fine. Raising scares weaker hands and only gets called by stronger hands or draws.
