they all contain billions of stars that orbit the center of the galaxy. all galaxies are also moving very slow.
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
All stars and galaxies are in the universe.
No. Some galaxies are shaped differently (irregular vs. spiral vs. elliptical), some spin in opposite directions, and some are bigger than others. However, they all contain stars and possibly solar systems.
Both have a huge black hole at their center.

Approximately 60% of all galaxies are spiral
They are ALL galaxies.
Both are spiral galaxies.
The collection of all visible or detectable galaxies is known as the universe. Each galaxy is a vast collection of stars--billions of them. Some galaxies have trillions of stars.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.
