No collision between comets has ever been observed. Considering their small
size, such collisions are very improbable. And considering that a comet emits
no light and most of its orbital revolution takes place in the outer solar system
where it cannot be observed, the probability of our observing such a collision
is virtually zero.
Small pieces of rock from old broken up comets become asteroids. Asteroids are large moving masses that can break up into smaller pieces. They break up and form meteorites.

It is called weathering.

Yes they do. The planet and moon pieces brake off and form a comet, just like a star is created by gas and dust.

The term used to describe the breaking off is calve. The pieces, after they have broken off are called icebergs.
