Adding a bit more: Yellow Dwarfs and Red Dwarfs are most common throughout the universe, our sun being a Yellow dwarf.
You've then got Red Giants, stars which have expanded to be 100x their original size, the Blue Giants, which burn up Helium. Supergiants, which are the largest known star, can get as big as our solar system, although these are rare. When they die they become black holes.
White dwarfs are small stars, about the size of Earth, but are much, much heavier. Eventually they lose heat and become a Black dwarf. Brown Dwarfs are stars that cannot have Nuclear Fusion occur at the core, and so are not very luminous. Neutron stars are very small, super dense stars and is mainly protons, with a diameter of 5-10 miles and density of roughly 10 15 gm/cm3.
