A sun is a star. A star isn't always a sun. There are probably millions of suns beyond our own. The definition of a sun is merely a star that has a planetary system around it, like our Solar System.
By the way, in no way are we seeing "planets" in what we think are stars. Sure, there are a few, such as Venus, Mars and the others in our Solar System that can be mistaken with the naked eye to be stars, but there are no planets beyond our Solar System that we look at and think are stars. They are simply too far away, too small and too unreflective to see. In other words, with the exception of our own Solar System's planets (and satellites, etc.), everything that we think of as a star IS a star.

Is your definition of a sun a star with planets in orbit around them? If the answer is yes, then it is known that some stars are suns. Any star is so far away that it is impossible to view the planets directly, but any star with planets orbiting it will " wobble" a bit as it is observed. This is what planet hunters look for. To the best of my knowledge, the planets that can be detected at this time are as big as Saturn and Juipiter. In time this will probably be improved upon, but planets have been detected orbiting distant stars.
All stars are giant balls of gas fueled by nuclear fusion at their core. in this respect they are all the same. Some are much larger and hotter(blue giants), some larger and cooler, (red giants), and some are small and cool,(white dwarfs), but all are stars. Our sun is just an average run of the mill star. Hope this helps.

Some of the other stars seem to have planets in orbit around them but it's not clear if all stars have planets that orbit them. It seems unlikely that binary star systems would have planets since they would either be torn apart or sucked into one of the stars.
Of course, if God wanted a binary system to have planets, then there are binary systems with planets. Look how precisely He put the earth in orbit around our sun so that the temperature is just right for life and seasons and everything else.

If it is a star, technically it is a sun... The only issue is, as we look out at the stars, something we see as a star, may infact be a planet but to us it just looks like a star.
So again, if it is a star and not any other planetary body, asteriod, etc.., then it is a sun.
Am I right astronomers??

Sun is just the name we gave our star

actually its depends on the age of a star the sun is in the middle age or maturin age of stars all stars necessarily need not be suns and the sun has planets rvolvin around it cause ven it vas it gave out dust and debreis and thaat vat formed the planets
