gotta know for my coarse

The sun is a star. Stars group together to form galaxies, and they dominate the visible universe. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth, including daylight. Other stars are visible in the night sky, when they are not outshone by the Sun.
The earth is part of the solar system. All the planets in the solar system orbit the one star we call the sun. So, no we only have one sun in our solar system but we have many other suns/stars in the universe.

Coarse? As opposed to fine?
Oh, you meant "course" like in a class or school.
So let me ask you this. When you go outside on a nice sunny day, how many suns do you see in the sky? Only one, right? That's because the earth orbits a single sun.
Not sure what the addition ".in our universe." part is about.
The universe has billions of galaxies each with billions of stars, but the earth only orbits one star in one galaxy.
I think you need to do a bit more reading for your course.

In our universe there is a basically infinite amount of suns. I am assuming you mean our solar system. Yes, there is one sun, but there are some theories that there could be a second star made out of dark matter (matter that cannot be seen), yet I am unsure if that theory was about our solar system. And, if you are talking about our galaxy, there is more than one, a rather large amount if I recollect correctly.

emmm... the earth has one moon, but the sun is for all the planets, the earth doesn't have it; it just revolves around it.
And no, there's only one sun in our solar system. In the universe, however there are millions of 'suns' (i.e. stars) and some are binary (which means there are two stars that revolve around one another) and the planets orbiting around those stars will have two suns.
As for our sun - let's keep it local for now - the sun is on its own, BUT thanks to Jupiter, it has an actual orbit around its barycentre (but that's physics, why that is... ask Einstein, he knows. It has something to do with the attraction of two bodies of great volume; Jupiter is the biggest planet in our solar system)
The barycentre is the gravity centre of an object in astronomy. So the sun does orbit around something, but it is not another sun... so, no. There is only one sun in our solar system.

Universe? don`t you mean Solar System. Are you trying to tell us that you are studying Astronomy and space and don`t know about our solar system?. "gotta know for my coarse"? do you mean "Course"? Come on get a grip.

No, we only have one true 'sun'. But Jupiter is what's called a 'protostar'. If it had several times the mass that it currently has, it would probably have enough to sustain the fusion reaction that is a star.

The earth has 2 suns... forget everything you learned in school.... we were taught an agenda that does not have you best in mind.

No. The Sun is the only one. There is no companion star to the Sun.

no the earth has only 1 sun.after 4.5 billion years the sun will explode and every planet in our solar system will explode too including us.goodbye=+)

No.. there are 9 (now 8) planets and 1 sun! and many moons
(in our whole galaxy)
but in a universe... there are many suns , which are also stars!
Glad to help you!
