In an indirect way, yes. Gama rays are the highest-intensity form of electromagnetic energy. They usually indicate a very power energy source. Most black holes are formed by exploding stars called supernovas. These events can be detected as gamma ray bursts.
No, but Hawking radiation does leak out from it.
Strictly speaking, gamma rays don't exit a black hole; they are electromagnetic radiation just like visible light - although they carry a higher energy - and neither light nor matter can exit a black hole. However, a black hole can cause gamma radiation to be created near it - for example, by processes at quasars or active galactic nuclei, which, powered by a supermassive black hole, can generate immensely powerful jets or beams which can accelerate particles to relativistic speeds, boost lower energy photons, and generate powerful x-rays and gamma rays. Another possible source of gamma rays is the so-called black hole evaporation, through which a black hole could potentially lose its mass and end its life with an explosive gamma burst.
One common term used is black hole evaporation. This relates to a mechanism wherein the black hole's mass is gradually lost through Hawking radiation; but the rate of loss is inversely proportional to the black hole's size and thus accelerates as it shrinks. At the moment it vanishes it is thought to do so with a burst of gamma radiation; the Fermi space telescope is intended to search for such gamma flashes.
Just like any matter, light or other electromagnetic waves (this includes gamma rays), if they happen to get within the black hole's event horizon, will just get absorbed, slightly increasing the mass of the black hole.
* Nothing can survive a black hole. Some people think if you put 1 million objects in a black hole, they survive the event horizon(edge of black hole) but only one survives the singularity(the point where the othere 999,999 are crushed into atoms).
They will merge to form a single black hole with the combined mass of the town that merged.
The gamma rays would be absorbed, the black hole's mass would increase.

Unless scientists were to detect the gamma-ray burst that might herald the birth of a new black hole, there is not even a theoretical way to measure the age of a black hole. So the answer to this question, like so many questions in astrophsyics these days, is "We don't know".

It's only infinite around the event horizon.
No. Nothing can pass through a black hole. Once something enters it can never leave.

Black Holes end up producing large quantities of gamma rays throughout their lives. This is one of the processes that lead to a Black Hole's demise.
No. Gamma rays are light, and the only thing that can "hold" light is the "inside" of a black hole's event horizon.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
