None, because Nibiru doesn't exist.
Those that support the Nibiru myth, and believe Nibiru to be a large terrestrial planet (there are many different beliefs among Nibiru believers as to what Nibiru actually is), often claim that it has 18 visible moons.
Nibiru's alleged orbit of 3,600 years is a claim without scientific evidence. However, if we assume it does exist, its distance from the Sun would depend on the specifics of its orbit shape and size, which are unknown. Without accurate data, it is impossible to determine the exact distance of Nibiru's orbit from 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.
63 known moons orbit Jupiter.
No planets orbit around Mars. There are two moons that orbit around Mars.
There are 4 moons that orbit around the planet Jupiter. The moons are Io, Europa, Ganymede, and Callisto. They vary in size and composition, with Ganymede being the largest moon in the solar system and having its own magnetic field.
Nibiru doesn't exist and neither do its moons.
The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
27 moons orbit Uranus that we know of

169 moons.
There are no known moons in orbit around Venus.
There are 180 moons in our solar system.
62 moons orbit Saturn, 67 orbit Jupiter, 5 orbit Pluto, 14 orbit Neptune, and 27 orbit Uranus.
Only one. The Moon

Mars itself is a planet. If you are asking how many moons it has, it has two moons that orbit it.
