Saturn is a planet. I think you mean moons. Saturn has about 63 moons. I say about, because it may have more.
Jupiter is the planet with the most moons in our Solar System. As far as the Universe goes, we can barely detect extra-solar planets, so there is no way to actually say what planet in the Universe has the most moons. Since we don't know about all the planets, we *definitely* don't know about all the moons.

Asteroids orbit the sun. Moons orbit planets and planets orbit the sun. So you could say the moons orbit the sun. However, moons are kept in their orbits by the gravity of their planet and planets are kept in orbit by the gravity of the sun. So in that sense, moons do not orbit the sun.
