The only event that we know of, that might result in a black hole, is a Type II supernova.
The event horizon of a black hole is spherical.
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.
This is usually considered to be the event horizon.However a spinning black hole spinning fast enough or a charged black hole with high enough charge might not have an event horizon, leaving just what is called a naked singularity.
The photon sphere is a sphere above the event horizon in which light orbits the black hole.
No. Only a black hole has an event horizon.

That refers to a black hole - but a black hole is not exactly a star.
if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.

its called the event horizon
The event horizon of a black hole.
The speed of light is a constant, it does not matter in or out of a black hole.
No, to be pink it would have to emit light and no light can escape a black hole's event horizon.
