And that was the jist of it. So how is my style of play? Overly agressive after the flop? Be gentle, I'm a novice :?

Hand 1 - fine.

Hand 2 - shove preflop. You have ~10x BB and any ace is a good hand heads up. In any case, don't minraise - you give opp too good odds to call you. As played, when you flop the nut flush draw, just shove over. Burning 40% of your stack here then folding the river when you've got ~10x BB just isn't good.

Hand 3 - I would shove preflop. You have a good hand and opp isn't showing any strength. As played, the flop check is OK but I would lead the flop for 600 or so. You have a very strong hand HU, build a pot with it!

Hand 4 - I would just shove preflop.

Hand 5 - good play. You just got unlucky after dominating opp.

Hand 1 looks good, hand 2 I would push, hand 3 I would check preflop and then lead out the flop for 600, hand 4 is a push, and hand 5 is good.
