Well blue stars are not as hot as red stars ,so the hotter they are the more they last, just like a red star.
No. While blue stars generally do not last as long as others, it is possible to find relatively young yellow or red stars.
Blue stars can be expected to be young as they do not last as long as other stars do, often only a few million years. That said, a lower mass star could still be just as young.
The biggest stars last only millions, the medium-sized stars last billions, and the smallest stars can last trillions of years.
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
Only very massive stars are blue. This is because they must burn hotter to resist the crush of gravity due to their large masses. They burn very hot, but also very fast so they have much shorter lifespans than less massive stars do. Therefore, blue stars are young because they become red supergiants and then go supernova fairly rapidly in star lifespan terms. They just do not last very long in the blue giant stage, so those stars, like Rigel in Orion, are young stars. If they were not, they would be red supergiants or neutron stars or black holes by now.

The U.S. flag has three shapes on it: the blue rectanglethat has the stars on it and the 13 long rectangular stripes that are red and white.
White - 1,295 miles long Blue - 870 miles long
Such stars usually last about 10 billion years.

There are two reasons. First, it is fairly unusual for enough gas to gather in one place to form a blue star. It is easier for small amounts of gas together, especially since a star will tend to drive away nearby gas once it forms. Second, blue stars to not live nearly as long as less massive stars do. So if a group of stars of various masses forms together, the white, yellow, orange, and red stars will still exist in 100 million years but the blue ones will not.
A lifetime.

Red Dwarf stars. Massive stars are also quite common, but stars like that (e.g. R136a1) don't last very long.
