how many stars are there in existance?

No one can say for certain. Matter of fact we don't know exactly how many stars there are in our own Milky Way Galaxy. Most guestimates for the Milky Way run to about 250-billion stars. Then there are about 250-billion other galaxies in the observable universe, each with more or less 250-billion stars each. A reasonable ball park figure for total number of stars in the observable universe would be approximately---approximately!---   5^22. That's 5 followed by 22 zeros.

there are several (you did not provide enough details)...could be a sun, galaxy, nebula, etc.

There are hundreds of billions of stars in our galaxy. If just one in out of every million of those had planets, and if just one of every million of those had life, and if just one of every million of those had intelligent life, then there would be literally millions of intelligent civilizations out there, just in our galaxy alone. And there are many billions of galaxies. If it is just us, seems like an awful waste of space.

There are 81 stars in the constellation Orion:\n\nStars with apparent magnitude of brighter than 3: 8\nStars visible to the naked eye: 75

Multiple star systems are very common. In fact, the closest star to us (Proxima Centauri) is part of just such a system. It was once believed that planets couldn't be in multiple star systems, but of the 166 extrasolar planets so far found, several are in such systems.\n\nAs for our solar system that seems to have just one star, a persistent theory continues that the sun does have a companion star that has an orbit so highly eccentric that it approaches the sun once in several million years. To date, no hard evidence for such a star exists. Also, if Jupiter had more mass, it would have at least started its life as a brown dwarf star.

Thats one of the funniest questions I've ever heard, and definately a first.\n\nRatio...lol \n\nEven if someone could give you an accurate number it would be too large a number on the star side to even begin to comprehend, and too small a number on the freckle side to even be able to comprehend.  No one knows the exact number of stars, or even galaxies that contain them.

there are nine planets in the solar system. it is not know yet how many planets are there in the entire universe, because we just know about 3 galaxies (and still do not know about any planets in galaxies other than the milky way)

It is estimated that there are approximately 200 million stars in the Milky Way and each one has the potential to have a "solar system" of some type.  Depends on many factors and the type of planets that can exist around a particular star also have many factors.  A number of "solar systems" have been found around other stars.  A current list of them can be found at exoplanets.org

Consider this there are billions upon billions of stars in each galaxy we are just 1 galaxy and there are billions upon billions of galaxy's in the universe. So the question should start with the universe.

Take into consideration the billions of stars in this galaxy. Then take into consideration the billions of galaxies in the local cluster. Then take into consideration the billions of clusters in the local supercluster. Then take into consideration the billions of superclusters in the local segment of the wall. Then take into consideration the billions of segments in the Great Wall. Then take into consideration the billions of walls in the Universe. It's even possible there's more than one universe! \n\nWhat do you believe? I think there is life out there. But are they sentient and advanced? Maybe. Maybe not.

At least 100 billion galaxies are known to exist in the Universe. Our galaxy is a spiral one, so in terms of structure it consists of galactic core and several spiral arms. In terms of composition it includes stars, planets (made from regular matter, including atoms of all naturally occurring elements and ions), galactic gas and dust (made from regular matter, mostly hydrogen and helium as far as the gas goes, and hydrogen, carbon, silicon, oxygen and some other elements as far as the dust goes), dark matter and dark energy (there is little known about the last two).

Accepted by the astronomical society, 88 constellations with their boundries outlined so as they encompass the whole sky.  Due to the imagination of people, you can probably see other pictures in your mind, but even then the sky is full.  Stars can be part of more than one constellation, the quickest example is the union of pegasus and andromadae.

There are approximately 100,000,000 stars in our Galaxy. Most stars are in binary or trinary systems. I'll guesstimate the number of stars in binarys is, oh...50,000,000. The answer is clearly in the several tens of millions.

A recent scientific study estimates that there are AT LEAST 70-sextillion stars in the universe, one of which is of course are own sun. The odds AGAINST none of those other stars having planets occupied by sentient life are astronomical (pun intended). Undoubtedly of all the life forms that exist in the universe some are technologically at the same level as we are, while others are at least several thousand years ahead of us. Still others might be where we were 3-million years ago---just down from the trees. Certainly, any alien life with any intelligence at all must wonder if there are other life forms somewhere other than their own world.

Number of atoms in the universe:\n10^11 galaxies * 10^11 stars in each * 10^33 grams in each star * 6x10^23 atoms of hydrogen per gram = about 10^79 atoms.  There are probably more photons but photons are so. . . insubstantial. Neutrinos?  Well, you ever try to catch one? They are only slightly easier to find than ghosts.

There really is no "star". There are characters who play a bigger role, but they all are "stars". It would depend on your point of view.

If you rely on the law of probability, then my opinion would be yes. This of course has not been proven, however, with more than 16 Billion other stars such as our sun in the Milky Way Galaxy. Let's say only a quarter of them have stable planetary orbit systems. That is still 4 BILLION opportunities for life. Now if we broke that down and said that only 1 % of those solar systems had a chance for intelligent life of some sort, that would still be 400,000 opportunities! I am speaking of our galaxy alone. There are 250 Billion Plus other galaxies with similiar potential. Alone???? I think not!
