Yes (since 1801).
The Oort Cloud
Yes (since 1801).
No. There are other asteroid belts besides the main asteroid belt in our solar system. Also, there are asteroids outside our solar system.
The Oort Cloud has not been directly observed by astronomers, while both the Main Asteroid Belt and the Kuiper Belt have been observed and studied. The Oort Cloud is a theoretical region of icy bodies beyond the Kuiper Belt, and its presence is inferred from the trajectories of some comets.
There seems to only be one major asteroid belt in our solar system. In-between Mars and Jupiter. Edit: There are technically 4. "The asteroid belt" between Mars and Jupiter, the "Greeks and Trojans" that follow along Jupiter's elliptical, the Kuiper belt, the final one, is quite far out and though it is effected by our Sun's gravity. It is called the Oort field and orbits between 5,000 and 100,000 AU's from our solar system.
The main asteroid belt is actually called the asteroid belt - pretty dull really.

1411 Brauna (1937 AM) is a main-belt asteroid discovered on January 8, 1937.
There is no specific asteroid named "Abai" that is widely recognized or recorded in scientific literature. It is possible that "Abai" may refer to a fictional asteroid or a lesser-known one that has not been extensively studied or categorized.

Asteroids. There are many thousand in the Main Belt that occupies an empty orbit between Mars and Jupiter. The largest asteroid, Ceres, has been classified as a "dwarf planet" and contains about 1/3 of the total mass of asteroids in the Main Belt.
Mathilde is an asteroid. It is a main belt asteroid that was discovered in 1885 by Johann Paliisa.
