Depends on the viewing conditions. There are about 5600 stars with an apparent magnitude higher than 6, which is usually taken as the limit of naked-eye visibility. In exceptionally dark locations under exceptionally good conditions, people with very good vision might be able to see all the way down to magnitude 8, and there are about 45,000 stars brighter than that.
However, nowadays, there's so much light pollution that for most people they're going to be doing good to get to 4th magnitude, which means they might only be able to see around 500 or so stars.
Those are total numbers. At any given time from any given point on Earth, at most around half that would be visible (the other half being below the horizon at the time).
Mercury, Venus, Mars, Jupiter, and Saturn can be seen with the naked eye.
Alpha Camelopardalis is 5000 light-years from Earth, one of the most distant stars that can be seen with the naked eye.Beta and Sigma are both double stars.
Mercury, Venus, mars, Jupiter and Saturn can all be seen from earth. They look like bright stars with the naked eye.
They can be seen in telescopes. At least three galaxies can be seen with the naked eye, but individual stars are normally too faint to be seen. However, in the case of a supernova explosion in a nearby galaxy, it could be seen with the naked eye, too.

Venus
The big dipper has 7 visible stars. There are really 8 but only 7 can be seen with the naked eye :P
Anything that is too far away or doesn't emit enough light. No planetoid can't be seen with the naked eye. Most stars, even the closest ones, can't be seen with the naked eye, since they are too faint to be seen - the stars that you do see have an above-average brightness. Comets - such as the ones in the Oort Cloud - can't be seen even with telescopes, unless they happen to come fairly close to us. The farthest known galaxies can be seen with large telescopes, but the individual stars cannot be seen. Etc.
a stars brightness as seen from Earth
no , to far for the naked eye !
lots of people well i seen my naked many times but in not get in trouble
No. Approximately 6000 stars can be seen with the naked eye, but there are many trillions of star out there that we can NOT see with the naked eye. Even the closest star after the Sun - Proxima Centauri - can't be seen without telescopes.
