There are approximately 100,000,000,000 galaxies in the visible Universe.
To name them all, at one a second would take about 3,169 years.
So I won't bother.
See related question for some of them.
To the best knowledge, there are an infinite number of galaxies, which means they don't have names!
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. See related question.
Elliptical, Irregular, and Spiral
All stars and galaxies are in the universe.
M87 is one of the most prominent galaxies followed by the elliptical galaxy Messier 49.

the universe is made up of galaxies
Galaxies in the universe have different names based on their shape and structure. Some common types of galaxies include spiral galaxies, elliptical galaxies, and irregular galaxies. Each type has its own unique characteristics and features.
There aren't really any other names for a galaxy that I can think of, but there are galaxy classifications, such as spiral galaxies (that can rotate either clockwise or counter-clockwise), elliptical galaxies, and irregular galaxies.
Approximately 60% of all galaxies are spiral
They are ALL galaxies.
