No. Haumea is a dwarf planet and in terms of composition is more similar to a comet.
The asteroid belt is mainly composed of rocky and metallic asteroids, so if it formed into a planet, it would likely be a terrestrial planet similar to Mars or Earth. It might have a solid surface, rocky composition, and possibly some metallic elements.
An asteroid is not considered a moon because a moon is a celestial body that orbits a planet, while an asteroid is a small rocky body that orbits the Sun. Moons are typically larger and have a more regular orbit around a planet, whereas asteroids have more irregular orbits and are not bound to a specific planet.
NO.
No planet ever existed where the asteroid belt is. The mass is insufficient for a planet to have formed from all that debris.
The asteroid belt is not in Jupiter.

The Planet Jupiter is between the planet Saturn and the asteroid belt. On the other side of the asteroid belt is the planet Mars.
