It's not an easy answer, basically... If it isn't true there soon will be and if it is true than it has most likely exceeded it. There is a small nebula that actually functions as a "star factory" creating thousands of stars from highly condensed gas. If one of these stars were to become a red giant and reach hypernova state, then It would become a Super massive blackhole capible of becoming a galaxy using all of the surrounding stars. The universe is still expanding so where ever all that radiation and matter ends up, it will surely cluster into another galaxy, from science's point of view, the possibilities of the universe are infinite.
Yes, galaxies can be any size and shape.
In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.
Because irregular galaxies have no definite shape.
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

Yes galaxies emit light
Yes, galaxies can be any size and shape.
The estimated number of satellite galaxies, given that there are 100 billion galaxies in the universe, is 170 billion.
The universe contains countless galaxies, think of the universe as a galaxy of galaxies.

There are approximately 7 trillion dwarf galaxies in the universe.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.

The observable Universe is estimated to have around 1011 (a hundred billion) galaxies. The entire Universe is much bigger than that, but it isn't known how much bigger. Perhaps it is infinite, in which case it might have an infinite number of galaxies.
