What is an active black hole?
An active black hole is a black hole that it by all manner of terms is "feeding". That is, it is accreting matter, or sucking matter into itself. Most black holes are dormant and don't show any signs of accreting matter.

Black Holes' can 'eat' any type of matter in the Universe.

Are there any black holes in your galaxy?
Yes. There is a supermassive black hole at the center of the galaxy and a number of stellar mass black holes through the rest of it.
Where are the micro black holes located?
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.
Does a galaxy contain black holes?
Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).
Why is the lack of direct evidence for black holes a problem for scientists?
There is enough evidence for black holes - I don't see any problem there.
