Stars are born in areas of space that contain a high enough density of molecular hydrogen to cause fusion. These areas of space are known as molecular clouds and are the locations in space where the majority of stars are created.
There are billions of galaxies. Most stars are born in one galaxy but others are pulled in by the huge gravitational forces of the black hole in the centre.
the color of most of the stars in our galaxy are white. They are concered white dwarfs
You will need to expand on that question. If you mean how many stars are born in a galaxy then it would be inaccurate for me to give an answer because a galaxy is a vast, heavy grouping of stars, supported by gravity. There is no minimum or maximum amount of stars allowed and so a galaxy could vary quite vastly in the number of stars it contains.
Our galaxy, the Milky Way, is a spiral galaxy (actually a bared spiral) and new stars are being born in the spiral arms.

A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
The most abundant type of stars is red dwarves.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
No, most stars you see are stars within our own galaxy, the Milky Way
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
Yes because stars are dying and being born constantly.
trillions If our galaxy with 2*1011 (two hundred billion) stars is an average size galaxy. and there are as many galaxies in the Universe as there are stars in our galaxy, then there are possibly 4*1022 stars in the Universe. But that is just a guess. There are most certainly more than 1018 stars.
