The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
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.

Not our (the Earth's) moon but Jupiter has lots of its own moons that orbit it.
