Yes, there are. Most large galaxies, for example the Andromeda Galaxy or our own Milky way, have a supergiant black hole at their core. Now, in the arms of our galaxies there are thousands of black holes. So, yes, black holes do exist in galaxies. Theoretically, a black hole cannot form outside of a galaxy, because to form a black hole you require either one or two superstars, and superstars do not form outside of a galaxy or a cluster of stars.

We have glaxies because our universe exploded.
The collapses star gets squeezed by collapses gas and turns into a black hole.
They're formed by gravity - and they look that way because they're millions or billions of miles away !
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

A black hole originated as a star, that is, the star converted to a black hole.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
If you fall into a black hole, you'll go into the black hole and nowhere else.

Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
