Yes, in fact everything in the universe rotates.
Rotation of picture
The Sun, all its planets and the galaxy in which the Sun sits all rotate.
biggest to smallest : universe, galaxy, star/solar system, planet, moon. The Universe is everything that exists and a galaxy is a cluster of billions of stars and then planets rotate around stars and moons rotate around planets.
Obviously. All galaxies must rotate - otherwise, they would collapse due to their own gravity.
It does. It rotates about its axis and revolves around the galaxy.
Nothing within human power can blow up everything in the galaxy.
The Milky Way galaxy is in a local group of 30 or more galaxies of which M30 or Andromeda and the Milkyway are the most massive and they center to a point somewhere between each other. Each have their own satelite galaxies that rotate with the major spiral dominant galaxy
No. If a galaxy were not to rotate, it would soon collapse upon itself, due to its own gravitation.

No. Everything in out solar system is in our galaxy, the Milky Way.
No. "Universe". We can see things outside our galaxy.
Each individual object (such as a star) revolves around the galactic center according to the laws of celestial mechanics. As a result, the objects closer to the center of the galaxy take less time for a complete revolution than the objects further out; the galaxy rotation is differential, meaning it does not rotate as if it were a solid object.
