No, most stars are not giants. The group with more stars is Main Sequence Stars.
Most medium mass stars such as our Sun DO become red giants. Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
Well light wise the highest category would be blue giants, red giants, and super red giants.
In stars and large gas giants.
Because they don't want to be blue tiny's.
Hyper giants live very short lives. Blue hyper giants end up as Wolf-Rayet stars most of the time.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
All stars eventually turn into Red Giants or Super Giants
Blue Giants or Super Giants
The Milky Way galaxy contains a variety of stars, including main sequence stars (like our Sun), giants, supergiants, white dwarfs, and neutron stars. The most common stars are red dwarfs, making up about 70-80% of all stars in the Milky Way. There are also many other types of stars, such as yellow dwarfs (like our Sun), blue giants, and red giants.
Yes. We have detected gas giants orbiting very close to their stars.
Stars spend most of their life span in the main sequence phase, where they are fusing hydrogen into helium in their cores. After exhausting their hydrogen fuel, they will expand and cool down to become red giants before eventually evolving into white dwarfs or other stellar remnants.
Red Giants. Stars not on the main sequence
