Yes, black holes are known and regarded by many scientists, astronomers, and physicists.
There are no black holes but there are dark areas known as Sun spots.
The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years. Of course, there may be black holes that are closer, but that are not known as such yet.The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years.

It isn't known whether micro black holes - usually called primordial black holes - exist at all. If they do exist, they can be at any random location of space.
Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.
Not sure what you mean. M60 is a galaxy. Just about all galaxies have supermassive black holes in their center - and lots of smaller black holes. The supermassive black hole in M60 is estimated to have 4.5 billion solar masses - one of the largest known black holes.
The densest stars are known as black holes.
For his scientific studies of black holes
1) It isn't known whether aliens (in the sense of extraterrestrial life) exist. 2) It isn't known whether wormholes exist. 3) No aliens are required to explain black holes; black holes form quite naturally as a result of the collapse of a massive star.
There is no known black hole in our Solar System.
It is not known how many black holes exist. One of the main reasons is that, if matter is not actually falling into the black hole, it is impossible to detect.
They definitely won't disappear tomorrow. Black holes are quite stable, and - for the case of known black holes - will last much longer than the current age of the Universe.
That is really not known. My theory is no, and apparently not. the black hole do not destroy but do not let out usual light, it do swallows the objects but it is not really known what happens next other than the swallowing, it is also known IN THEORY to be many black holes that is to small to be affected by around us too. and we also have wite holes.
