I think you are describing a "globular cluster", which are associated with older stars by most astronomers.
milky way is a spiral galaxy spiral galaxies have younger stars in the arm and older stars in the middle

Yes. Some spiral galaxies do contain at least 1 trillion stars.
A spiral galaxy is just a type of galaxy but I can tell you that the stars in the middle are the oldest and the ones on the outside are the youngest.
some are big.
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
No, a galaxy is a cluster of stars, some of which might have planets.
(Atoms) Stars, Dust.
