The primary fuel for all stars is hydrogen
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.
"main sequence" is the tern.
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
Stars leave the main sequence when they have exhausted their core hydrogen fuel, causing them to expand into red giants or supergiants. This transition marks the end of stable nuclear fusion in their cores and the beginning of the next phase in their lifecycle.

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
Main sequence star: hydrogen-1. Red giants: helium-4.
Main sequence star: hydrogen-1. Red giants: helium-4.

gas, and other vibrate radiations.
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.
There are billions of stars that are not on the main sequence.
Hydrogen is being "burned" into helium.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
