There are about 200 -> 400 billion stars in our Galaxy
trillions of other stars in the milkyway
yes
Yes, stars can exist outside of a galaxy. These stars are typically referred to as intergalactic stars, and they may have been ejected from their original galaxy due to interactions with other stars or galactic dynamics. Intergalactic stars are typically found in the space between galaxies.
Stars are suns, We are in the Milkey Way Galaxy, We have only one Star. There are BILLIONS and BILLIONS of Stars in space.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
No. The sun is a star like any other; it holds no special place in the galaxy. The stars, including the sun, orbit the center of the galaxy. There are also stars in other galaxies.
The other "solar bodies" are called stars.
Even though they travel together they are kept in the galaxy by the galaxy's gravity, which is the combined gravity of all other stars, nebulae, and other matter in the galaxy.
