It depends how good you are at looking for them. If you look up into the night sky from a city, with air pollution and light pollution, maybe a few dozen. If you go into the countryside and wait about 20 minutes for your eyes to get accustomed to the dark (with no streetlights of course), significantly more. If you have binoculars or a telescope, even more. There are roughly 100,000,000,000 stars in this galaxy alone. I don't know how many there are in the observable universe.
