Turn: raise $9 --> Try to maximize the pot and your winning against these kind of weak players.
River: I would raise against these kind of player. He is week, and this bet seems to be a protection bet (please dont raise big...). Though he might call your reraise here with a pair or with his other weaker hand.

Raise bigger on the turn.

Call is fine on the river. I wouldn't raise.
