On a good clear night away from city lights and haze for a person with ordinary eyesight, about 3,000. For a person with a telescope, thousands more depending on power of telescope. Some of the things you see as stars are galaxies where you can't make out individual stars but telescopes show that there are tens to hundreds of thousands of stars in each one.

Mike's answer is pretty good. There are 2000 to 3000 stars visible in the night sky to a person with decent eye sight, unaided. Perhaps 1000 at any one time, 2000 if you counted them all night long (new stars swing into view as the earth turns), and perhaps some 3000 over the course of a year.
These are just rough numbers. If you live in a light polluted city, you may be able to see only half a dozen stars. Out in the country, the glow of the milky way is the light of millions of suns. Our galaxy contains some 200 to 400 billion stars. Beyond our galaxy there are another hundred billion.
(100e9)(200e9) = 20 sextillion (2e22) stars in the universe [approximately] This is the product of 100 billion galaxies and 200 billion stars per galaxy. Many galaxies are smaller than ours, and some are much larger. I use 200 billion stars per galaxy as a rough average.

Is your question, how many do we see with the naked eye on a dark night at higher elivations like 7,000 feet? Maybe 10,000.
It all depends upon your deffinition of sky.
We see a tiny, tiny speck of our Galaxy. (With it's 200 billion stars M/L.) Or are you asking about stars with in the universe?
Thats the big sky. A trillion M/L. Milkyways or Galaxies with 200 billion M/L stars average. Now how many stars are dark that we can not see? A very round figure of 25 trillion times 200 billion. (no body knows exactly, or with in trillions of any guaranty)

A lot of wrong answers here. There are literally trillions of stars in the sky, but only a few thousand are visible at any one time, depending upon latitude and longitude, elevation, cloud cover, surrounding lights, etc etc.

The answer is 0. "Sky" is part of the Earth's atmosphere.

Only God knows Asteria, we mere mortals don't have the ability to count the number of stars. We may as well try to count the grains of sand on planet earth.

About 3,000 visible stars.

A finite amount, given that the mass of the universe is finite.

As many as you can see... you see madam, there are zillions of them up there including what you can't see. Get it, get it?
