That sounds like the description of an elliptical galaxy.
It is called simply a "globular cluster". Another possibility: The closely allied stars at the center of a galaxy tend to be older, redder stars than those in the outlying arms of the galaxy.
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.
The universe comprises all matter in space. This includes a very large number (200 billion to 2 trillion) galaxies. Each galaxy comprises a very large number of stars: our contains 100 thousand million stars.
Generally older stars are towards the middle of a galaxy whereas younger stars are towards the edge.

Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
Milky Way: Arms extend from a core full of black holes Elliptical Galaxy: Contains mostly older stars with a red color Irregular Galaxy: Contains dust, gas, and young stars Apex :)

Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
No. A Galaxy contains billions of stars whereas a binary star contains only two stars.
Yes. An average galaxy contains at least 100 billion stars.
By analysing the oldest stars found.The older the star, the older the Galaxy.
Yes. A galaxy contains many stars.
