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.
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.
No. That is when stars run out of hydrogen. They then have helium for fuel.
The five main groups of stars are main sequence stars, giant stars, supergiant stars, white dwarf stars, and neutron stars. These groups are classified based on their size, temperature, and stage in their life cycle.
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.

Yes.Red giant, star that is relatively cool but very luminous because of its great size. All normal stars are expected to pass eventually through a red-giant phase as a consequence of stellar evolution. As a star uses up its hydrogen by converting it to helium, its central core contracts while the outer layers expand and cool; this process produces the low temperature and large size (from 10 to 1,500 times that of the sun) that characterize the red giant. Although most giant stars are red, some prominent giant stars are other colors near the red end of the spectrum, e.g., Arcturus(orange), Aldebaran (orange), and Capella (yellow). The largest and brightest stars (excluding supernovas) are classed as supergiants. Red supergiants, e.g., Betelgeuse and Antares, are old, highly evolved stars.
