Assuming you mean the event horizon of a black hole (there are other types as well), the diameter of a black hole as measured by its event horizon is directly proportional to its mass. The larger the mass, the larger the diameter. Thus, as a black hole's mass increases, it will get bigger. The only limitation is how much mass a black hole is able to incorporate from its surroundings.
it depends on the size of the black hole. the larger the black hole, the farther the event horizon will be from the start of the black hole.
No. Only black holes have event horizons.
I think study of event horizons of black holes is quite interesting. Many also like looking for planets in other systems.
The New Horizons spacecraft is currently over halfway to Pluto, and set to arrive in 2015.

The event horizon of a 100 solar mass black hole would be 2.95x105m.
Event Horizons BBS ended in 1994.
Event Horizons BBS was created in 1983.
No. Only black holes have event horizons.
An event horizon starts at precisely the moment a singularity does. The event horizon isn't so much a thing as a place. Like the Earth's Equator. It is the result of the singularity's gravitational pull and it will remain as long as the singularity does.
there are 4 horizons
