By measuring it's gravity. The faster things are orbiting the black hole, the more gravity and the more mass it has.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
Scientists calculated indirectly the mass of a black hole by the behavior of matter around it, from which its gravitational pull can be determined, and with an accurate measure of its distance, its mass can then be inferred. In some cases an upper limit can be calculated by the closest approach of a visible object observed near it; in this case, its size is a result of a direct relation to its mass since the radius of the event horizon is directly proportional to the black hole's mass.
The mass of a black hole can be measure by the effects of its gravity on surrounding objects.
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.

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.

Scientists are now largely convinced that there is indeed one at the centre of the galaxy... the evidence indicates a compact high-mass object there; if it's not a black hole, we don't know what else it could be.

The very center is believed to contain a very powerful black hole.
Such energy has a mass equivalent (m = e/c2). Any such mass falling into the balck hole will increase the mass of the black hole.

No. If no matter enters a black hole it will actually slowly lose mass and shrink via Hawking radiation. A black hole will gain mass if matter fals into, which will cause the event horizon to grow.
It is not yet known for sure how a supermassive black hole acquires the enormous mass it has. It is possible that it starts as a normal black hole, and then gets more mass. It is also possible that from the start, a much larger amount of mass than in a normal black hole collapses.
