Each asteroid has its own escape velocity.
Are you asking if there is a minimum velocity to escape the gravitational pull of an asteroid? The answer is yes. The second part is more difficult as it is variable, based upon the mass, size, and shape of the asteroid and where you start from. Assuming that the asteroid has no atmosphere, the necessary velocity would be roughly the square root of... double the universal gravitational constant, times the mass of the asteroid..., divided by the distance from the center of gravity.
The main asteroid belt is actually called the asteroid belt - pretty dull really.
Mars is not in the asteroid belt. The Asteroid Belt is between Mars and Jupiter.
The asteroid belt is in between Mars and Jupiter.
Venus is not in any asteroid belt.

Inner.

The planet Jupiter is outside the asteroid belt, which is located in between the orbits of Mars and Jupiter.
Yes, the asteroid belt starts properly after the orbit of Mars.
it is outside the asteroid belt
no its in the outer side of the asteroid belt
