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.
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, 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.
Blue white stars are more massive and burn through their fuel supply at a faster rate compared to red stars. Their high energy output causes them to exhaust their fuel more quickly, leading to shorter lifespans. In contrast, red stars have lower mass and hence a longer lifespan as they burn fuel at a slower rate.
There is no such thing as a cold star, as even the lowest-temperature stars are very hot. That said, cooler stars last longer as they burn their fuel more slowly.

As with everything, stars age as well, and reach the end of their time. As stars age, they become different types of stars, based on how big they are, and how hot they are burning. When they run out of fuel, they eventually die.
larger stars have longer lives, because as stars burn they are slowly burning up fuel and begin to cave in on themselves. the larger, the more fuel, the more fuel, the longer lasting.

No. They eventually run out of fuel and die, though this takes a very long time.
Young stars burn hydrogen (the lightest element), converting it into helium. Later they may convert helium into heavier elements.
The lifetime of a star is determined by its mass because more massive stars burn through their fuel faster due to higher core temperatures and pressures. Higher-mass stars undergo fusion at a quicker rate, leading to a shorter lifespan compared to lower-mass stars. Conversely, lower-mass stars burn their fuel more slowly, allowing them to exist for billions of years.
Well it is pretty simple, you burn it.
Your question is not very clear, so i will answer according to my understanding. There are different types of stars, all different in size and composition. Regardsless of this fact, one commonality exist between all stars, eventually they run out of fuel. Super massive stars are the largest in the universe and they consume their fuel very quickly after which they will detonate as supernovae; completely disintegrating themselves in the process. The longest living stars are Red Dwarfs. Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that they're much cooler than stars like our Sun. They have another advantage. Red dwarf stars are able to keep the hydrogen fuel mixing into their core, and so they can conserve their fuel for much longer than other stars. Astronomers estimate that some red dwarf stars will burn for up to 10 trillion years. The smallest red dwarfs are 0.075 times the mass of the Sun, and they can have a mass of up to half of the Sun.
