If so can they leave also?

No one's ever seen one. It's not even certain whether any comets have entered the solar system from interstellar space.

The answer is yes! The only problem is that asteroids and comets are made from the "stuff" left over from the beginning of the Solar System. Most of them are very similar in composition and any from anywhere else in the universe would almost certainly be similar. The gravity created by the Milky Way would pull any interstellar material toward it, and then the Sun could pick it up from there.

We can only slightly see or calculate a comet inside our own solar system. To be able to find one in the Milky Way is impossible at this point.
While I am sure they are out there, and have some crazy orbits. I do think they are most likely not able to be studied by people on earth at this point.

I would say no.
They probably don't even go from solar system to solar system.
You must consider time and distance.
I suppose a piece of material could have left or entered the solar system but it would be a stretch.

Don't know for sure, but comets probably do.

No they can't.
