All the bets seems fine, but they don't seem like bluffs to me. You could have the best hand in each case.

A bluff (to my way of thinking) is when you're pretty sure you're beaten and the only you can win is by betting. In these hands you don't know where you are, so you bet. (why not?)

On number 2, why 9 instead of 13? I'd be careful of not giving away information, as crocksucker has aluded to. The bet's fine as long as you would normally bet 9 with other hands.
