Draws come in
 

5/10, 5-handed, just sat down.

Hero dealt Ad5d in CO. All but button call to BB who raises, 4 to flop.

Flop 9d 4s 3d. BB bets, call, hero raises, fold, BB 3-bets, call, hero caps. 3 to turn. I will take free card on turn if given chance. Do I have enough equity for a bet if I don't improve?

Turn 9h. BB bets, call, call.

River Jd. BB bets, UTG raises, Hero 3-bets (?)

I think everything here is ok, but let me know if anything's wrong.

I'd probably raise preflop to capture the button and isolate the single limper.

Rest is good.

Isn't A5s (as far as an absolute hand value goes) a little too weak to do that?

I'd think I'd rather be among 4 and get away for cheap if I had to. I like OP's play.

I'm happy my thoughts are aligned with StellarWind's.
