re: Poker & I just started no limit.. how do you play against this type of player
Your notes aren't detailed enough, to be honest. I could be guilty of all of the notes except for the last one (I rarely, bordering on never, coldcall raises preflop out of the blinds).
For instance, bets middle pair: In position? How many players are still in the hand? Is he the preflop raiser? Does he donk middle pair? Raises with it? Checkraises with it?
On the whole, it sounds like a loose and somewhat aggressive player. Since his primary mistake is to play too many hands, you should tighten up somewhat (SOMEWHAT!) against him and then value-bet him to death, i.e. bet stuff like middlepair, good kicker where against a tight opponent you'd probably check/fold. But knowing that he plays T5s from the SB isn't useful, really. In an unraised pot with a passive BB, I'd often play that as well. If he plays it UTG, now that's a different story.
