are stars real ?

What makes you think they are fake?

Just like you and me are made up of atomic matter so does stars. Just like you are real, the stars are real.

Are humans real? Are cats real? Are trees real?
Of course stars are real. What made you think they were fake?

Yes

Stars are suns the same as our sun
, the first star, other than the Sun, to be directly imaged was Betelgeuse. It has an angular diameter of only 50 milliarcseconds There are 11 stars mentioned as being resolved on the Wiki site below. Milliarcseconds are one thousandth of one 60th of one 60th of one degree or 0.000000278 of one degree

Your question is a bit broad and could use a little clarification.
First, many, many people have seen stars, furthermore, they all seem to basically see the same stars over and over again, so they are not ghosts, nor do they seem to change much from one generation to another. People who do not know each other can independently make star charts, which can later be compared, so the stars are probably not figments of our imagination, since it passes the double blind test. People can photograph the stars over and over again.
I can see the stars, but I can't verify what they are. Might they be an illusion not too distant from our own solar system? Well if I (or generations before me have noticed spectral lines, in candles, the sun, neon lights, streetlights, arc welders and fluorescent tubes, then we can know what spectral lines go with what element(s). The spectral lines read like the bar codes of the visible universe. We can also tell how much spectral shift goes with how much velocity. We can test it out in the lab, then test it again on the international space station.
Now we have a pretty good idea what they're made of and how fast they're going. An even earlier thought process is: "How much dimmer than our sun is that star? Is that star a sun like our own? If so what would that difference in dimness mean in terms of distance?
The full moon is a million times dimmer than the sun. Yeah. Our human eyes compensate to make the full moon look as bright as it does.
So how far away would a star be that appeared to be one trillionth the brightness of the sun, but appeared to be the same temperature also?
Its face would take up one trillionth of the amount of sky that the sun takes up, so, its angular width would be the square root of that difference: square-root of 1000000000000 is 1000000 its a million times as far away as our sun... 8 light minutes * 1000000 = 8000000 Light minutes,
or about 15.22 light years. At that range they can also use parallax.
Take a good hi-res picture of the star, wait six months, take another one and compare the two. The star may even jump out in 3-D.
When it comes right down to it, the simplest explanation is that there are lots of fusion plasma-balls that work a lot like our sun that are widely scattered.
Their heat to brightness ratio follows some fairly straight-forward rules, namely, the bigger the star, the higher the gravity, and the harder it's squeezing the fusion fuel. Bigger stars generally shine bluer, littler stars usually shine redder (and are expected to live longer)
Answer: Yeah, stars are probably real.

Stars are cosmic energy engines that produce heat, light, ultraviolet rays, x-rays, and other forms of radiation. They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles.

Though the most familiar star, our own sun, stands alone, about three of every four stars exist as part of a binary system containing two mutually orbiting stars.

No one knows how many stars exist, but the number would be staggering. Our universe likely contains more than 100 billion galaxies, and each of those galaxies may have more than 100 billion stars.

Yet on a clear, dark night Earth's sky reveals only about 3,000 stars to the naked eye. Humans of many cultures have charted the heavens by these stars.

Are stars real? Absolutely! You I'm not so sure about!

Yes, by giving our awareness to those star we make them as real as anything else.

Are emotions real? not necessarily but we give them so much awareness and attention that they become real.

Fun fact, you look up at the night sky you see stars.
Those stars are not actually there. The light from those stars is refracted when entering the atmosphere so while they seem directly over head, they are actually more "in front" of you than "above" you

and most of those stars probably don't exist anymore, two years ago a friend and I witnessed a star disappear. We were blown away, we have seen that star every night for years and literally watched it flicker a few times then disappear and i no longer see that star. sure something could have gotten in the way, and there are many other explanations but its cool to think you actually saw something that crazy of an event, no matter the distance.

Taylor Swift, Hanover Pretzels, Yuengling beer. Yes stars are real!

Oh, you mean those extraterrestial lights out there. Some Christians call them fake. I dont know why.

yes, see them with a telescope. In younger years I have studied things like carpicorn of stars in a game... but I don't know much about the lore of these stars and planets. At night, stars appear, all you gonna do is to buy a telescope and see through it. You can do this with your family or your girlfriend. It's quite relaxing, you know.
