Yes red giants are the largest. But the bigger stars of red giants can be called red hyper giants.
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
A Red Giant Stars that are much bigger than the sun are the giants and of course the super giants, which are the stars with the biggest size. If you want a specific one, Betelgeuse or Antares would be good choices.
Red giant stars are the most common type of giant star primarily because they represent a late stage in stellar evolution for stars that have exhausted the hydrogen in their cores. As these stars evolve, they expand and cool, resulting in the characteristic red color. Since many stars in the universe, including our Sun, will eventually become red giants after exhausting their nuclear fuel, this phase is more prevalent in the stellar population compared to other types of giant stars. Consequently, red giants dominate the observed population of giant stars in the universe.
In the constellation Cetus, there are several red giant stars. These are stars that have exhausted their core hydrogen and expanded in size. One notable red giant in Cetus is Menkar, also known as Alpha Ceti.
The main fuel for red giant stars is helium. In the core of red giant stars, hydrogen fusion has ceased, and as the star evolves, it starts fusing helium into heavier elements like carbon and oxygen. This process produces the energy that sustains the star's outer layers and causes it to expand and cool, creating a red giant.
Red giants. By the way, what if it was a white star.
When compared to the other stars, the Red Giant Star are very minute. There are other stars that are very large by far as compared to the Red giant stars.
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
The oldest stars are now mostly either white dwarfs or neutron stars. A few of the largest may be black holes.

when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
Red stars are usually giant stars that are on the brink of death. It is said to be on its last stages of stellar evolution.
