mostly hydrogen.
and a number of other elements.
PS: a few other answers are correct, but most are incomplete or wrong:
1) stars do not "burn", the light comes from a reaction of nuclear fusion, not from something "burning", even if it still means that it's quite hot down there. "burning" is a chemical reaction, that is an exchange of electrons that changes the structure of matter at the molecular level. What happens is nuclear fusion, which changes the matter at the atomic level: it's not electrons who are moving from one particule to another, but protons.
2) yes, hydrogen is gaz, but NOT IN A STAR !!!! In a star, hydrogen isn't gaz anymore, it's plasma!
plasma is a state of matter, just like 'solid' 'gaz' and 'liquid', the difference is that when matter goes plasma, it becomes 'hot enough' for all its electrons to float away from it, allowing nucleuses to interact with each others and fuse together (protons from 2 atoms are added together to give 1 single heavier atom : fusion reaction)

Mostly Hydrogen. also some Helium as this is what the hydrogen fuses to to create the heat and light, in massive stars at the end of their lives lots of other elements are present such as oxygen and carbon etc that have been made by nuclear fusion

Mostly hydrogen, with smatterings of helium, lithium, and heavier elements, the latter depending on how much refuse they have accumulated over the millenia from supernova explosions in the neighborhood. Our sun has a fair amount of such debris, as does the earth, and it's a good thing because the heavier elements are essential to life.

A self-luminous Celestial body consisting of a mass of gas,( mostly Hydrogen & Helium ). Held together by its own gravity.

This really depends on the type of star and its age, but mostly light elements that fuse into heavier elements.

They are made of gas but they are suns like Red Giants which is bigger than our sun
