How long wiil the star give their light?
Stars live for various lengths of time mostly dependent on their size. Small stars live longer (up to many tens of billion years). Large stars live short lives (comparatively) only shining for a few hundred million or a billion years.
Which stars of the HR diagram are in open clusters?
Many stars which are members of an open cluster are blue, hot stars, with relatively short life expectancies (a few hundred thousand years to a couple of million years life).
Why are so few stars in both the table of Nearby Stars and The Brightest Stars?
I am pretty sure the table you consulted lists only the extremes - but of course you can have thousands or even millions of "near" stars and "bright" stars, depending on how far down the list you go. Note that any list of the first thousand (for example) nearest stars would probably be incomplete, since there are many dim stars (red dwarves) that are very hard to detect.
How much of a stars life is spent as a main sequece star?
Most of its active life, usually. The actual time may vary from only a few million years (for very massive stars) to trillions of years (for some red dwarves).
What is a grouping of stars that have a loose and disorganized appearance and contains no more than a few thousand stars?
Open Cluster
How many people are involved in making cheese?
Only a few. Sometimes only one.
How many photographers are there?
As many as stars in the sky!!! But only a few are professional photographers who can capture quality photos.
How many hyper giant stars exist in the universe?
Hypergiants are relatively rare. Only a few stars become hypergiants, and they don't last very long (only a few million years). Probably a few in every major galaxy.
How many stars does the Little Bear have?
A few!
How many stars are in the NGC 1427A galaxy?
No count of stars in any galaxy has been made. Estimates are given.Galaxies can contain as little as a few million stars or as many as trillions.NGC 1427A. A few billion maybe.
What is theLifespan of a housefly?

How many stars on the galaxies?
A dwarf galaxy can have a few million stars; a huge galaxy can have a trillion stars or more.
How many stars are in the solar system apart from the sun?
None. Our solar system is one of those rare few with only one star.
Are all stars white?
No. Many stars have a distinctly reddish hue, and a few are a little bit blue.
Is Betelgeuse the oldest star?
No, large stars like Betelgeuse only last a few million years. Our sun is older, at around 4.5 billion years, and there are many stars even older than our sun.
What would the nigh tsky look like if all-stars had same absolute magnitude as the sun?
If all stars had the same absolute magnitude as our Sun, we wouldn't see many bright stars. Many of the stars that seem brightest to use are far, far away, but thousands of times brighter than our Sun. Those are relatively short-lived stars, many of them will live only a few million years. (Yes, this is short for a star; many stars, like our Sun, have life spans of billions of years.)
Are there more heavenly bodies than the stars you see?
Yes. There are only a few thousand stars that are visible to the unaided eye. All of them are in one small portion of our galaxy, which contains an estimated 200 billion stars. Beyond that there are an estimated 100 billion galaxies in the known universe, most of which have billions of stars of their own. Many of the stars have planets orbiting them.
