Depends on how a galxy's size is compared to another one. Some galaxies are larger than others. But in light-year lengthwise, they are very big. A light year is equal to almost 6 trillion miles or 10 Pm (Petametre)
At the center of a large cluster, you'll usually find large and massive galaxies.
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
Galaxies get bigger by a process of merging. The gravitational attraction of the galaxy and the dark matter round it pull in satellite galaxies and these merge with the main galaxy. Eventually large galaxies merge to form large elliptical galaxies. look at the link below.
Not just dwarf galaxies. Giant elliptical galaxies lie likely the result of many galaxies, small and large, merging.
Large and Dwarf.
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.

If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
Canis Major Dwarf and Small Magellanic Cloud are irregular satellite galaxies of the Milky Way.The two irregular galaxies that orbit the Milky Way are the Large and Small Magellanic Clouds.
Yes, because scientists have found hundreds and hundreds of galaxies already and scientists say that there are more galaxies out there that they haven't found!
Between them.
