The term "weather" makes more sense for planets, than for entire galaxies.
There are zero galaxies in our Solar System. Even the smallest galaxies are much, much larger than the solar system.
Billions.
That is backwards, galaxies are much larger than solar systems.
There are several hundred billion galaxies in the KNOWN (or observable) Universe; the actual Universe, however, is believed to be much, much bigger.
A collection of from two to several hundred galaxies which are much more densely distributed than the average density of galaxies in space.
You don't. That's way too much. You just get the redshift of a sample of galaxies. As a clarification, the current estimate is about 170 billion galaxies - and that refers to the "observable Universe". The entire Universe is expected to be much larger than that (and have many more galaxies), but those can never be observed.
There are about 1011 galaxies on the observable Universe. The actual Universe is much bigger, but nobody knows how much bigger. Answer2: Thee are >1012 galaxies in the universe.

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.
Much more than that, actually. The number of galaxies in the OBSERVABLE Universe is at least 1011.
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
A galaxy is made up of hundreds of billions of stars (suns). The light from the galaxies comes mainly from those stars.However, in early galaxies, a much larger amount of energy was released from the quasar - currently believed to be the gigantic black hole in the center of galaxies.
