Main sequence star: hydrogen-1.
Red giants: helium-4.
Giant stars are commonly referred to as "giant" stars because of their large size compared to main sequence stars like the Sun. These stars are in a later stage of their evolution and have expanded in size due to the depletion of their core's hydrogen fuel.

The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
Main sequence stars do not really exist - well they do, but read on. Main sequence is a stage in a stars life - where it converts hydrogen into energy, not a particular star or type of star. All stars go through a main sequence, from the smallest to the largest.However, in general, the larger the star, the faster it will burn off it's fuel.
The primary fuel for all stars is hydrogen
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.
Giant stars are massive, luminous stars that have reached the later stages of their life cycle. They are larger and hotter than main sequence stars, like our Sun, and are often in the process of expanding and cooling as they exhaust their nuclear fuel. Giant stars are crucial for the creation of heavy elements in the universe through nucleosynthesis processes.
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
No. That is when stars run out of hydrogen. They then have helium for fuel.
main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star
Hydrogen.
