We have no way of knowing how many, although we do now know that there are other star systems with planets, or notable "accretion discs" (from which planets will form). It is a very difficult area to explore because planets, even very big planets, are a fraction of the size of the stars they surround, and the stars themselves are difficult enough to see. As far as "how many in the universe?" undoubtedly a large amount, but we have absolutely no idea how many that might be.
