All stars 'burn' 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.
Yes, young stars burn Hydrogen and produce Helium. As they age, they often turn into red giants, and at that time they burn the Helium, making Oxygen and Carbon. Very large stars can even burn the Oxygen and Carbon, making even heaver elements, such as Iron.
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.
Main-sequence stars; those are stars that are in a certain area in the H-R diagram. They are also the stars which burn (fuse) hydrogen-1, converting it into helium-4.
All main sequence stars fuse hydrogen.
Stars are mainly made out of hydrogen, they use it to burn.

Hydrogen is the primary fuel that stars burn. A star fuses two hydrogen atoms together to form one helium atom. Energy is released during the process that we see as light and feel as heat.
Because larger stars burn their hydrogen faster than smaller ones.
Most stars, for most of their existence, fuse hydrogen into helium.
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.
Young stars burn hydrogen (the lightest element), converting it into helium. Later they may convert helium into heavier elements.
Massive stars have much greater pressure on their cores, causing them to burn hydrogen (the fuel) more quickly.
