Stars shine because they are so extremely hot. Which is why fire gives off light. It is a process of turning one chemical make up into another chemical make up. In most stars hydrogen is being converted into a helium. The energy from this gives the star heat. This warms the outside of the surface of the star and the surface gives off heat and light. So you can say that stars are not on fire, even though they look that way, so they are not burning.
All stars 'burn' hydrogen
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.
Heavier stars will usually burn faster than lighter stars.
Yes, all stars run on a limited suppliy of fuel - mainly hydrogen. Some stars burn it very quickly but reach high temperatures, while other lower mass stars burn their fuel more slowly, lasting for longer, but burn at cooler temperatures.
Shooting stars are not stars. They are bits of dirt and dust that burn up in our atmosphere. As they fly through our atmosphere they briefly look stars, which is how the names shooting or falling stars have come about, but they are not stars. Were such a piece of dirt to head toward a star, it would burn up long before it got anywhere close to it, so it could not hit it. A shooting star is usually what most call meteors and burn up in earths atmosphere giving the appearance of a falling star.
All stars 'burn' hydrogen
Because even the smallest of stars are >1000 times bigger than the Earth, stars would not burn up in our atmosphere, but instead just annihilate everything in it's path, but there's no need to worry the closest star is16.308 light-years from the Solar System, and the universe is actually expanding so no stars are going to annihilate the earth.
Stars typically turn red before they burn out.
The color of the stars depend on how hot they burn.

yes because it can burn out

All main sequence stars fuse hydrogen.
Constellations are imaginary patterns in the sky formed by stars. As some stars burn out, new stars form.
