The 'Asteroid Belt' is composed of an unknown (but very high) number of Asteroids in an orbit around the sun many 10's of millions of kilometers in circumference.
This asteroids can collide or orbit for years without coming within a million miles of another. As a result the distance between one and its closest neighbor can be a few feet (or less) to 1000's of miles apart and this is changing all the time.
I do not believe the 'Average' separation has reliably been calculated, but the answer would probably be larger than a 1000 miles. This figure would include particles the size of a fist, or smaller, as well. As you include asteroids of only a certain size or larger; then the average separation would also get larger (since there are fewer and fewer numbers of asteroids as the size increases).
The same age as the rest of the solar system. Approximately 5.5 billion years.

Very not thick ...
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.

Yes, the asteroid belt starts properly after the orbit of Mars.

The planet Jupiter is outside the asteroid belt, which is located in between the orbits of Mars and Jupiter.

it is outside the asteroid belt
no its in the outer side of the asteroid belt
Ceres is part of the asteroid belt.
