you're going to have to clarify a little.
Although there are binary star systems that have evidence of planets, the current understanding is that it would be difficult for life to spawn if that was the case. However, it's interesting to note that many binary star systems do have planets.
If Jupiter was a little bigger, in theory Jupiter would've become a star and we would've have two suns.

The key word here is the term ecosphere. This is an area around a star where life can potentially exists. Obviously Earth is within the Sun's ecosphere and we assume that Venus and Mars are within this area too.
Now, a second star could have potentially disturbed the Sun's ecosphere on many occasions.
For example, what if that star was too close to us? Jupiter for example, could have been a second Sun if it was more massive. But this could have disturbed the Solar System's ecosphere, meaning life may not have existed on Earth if Jupiter were to ignite.
Also, for life to exist you need stable stars with predictable behaviour over time. Stars that do not emit high levels of ultraviolet radiation killing life. Our Sun, for example, is such a well-behaved star. But put another star in the Solar System that emits high levels of radiation or one that has an erratic behaviour and there goes life with it!
This is not to say that life may not evolve in stellar binary stars. It's just we don't know. After all, we have only one Solar System to study and we know of only one planet where life exists.

If there were more than one sun, then sol wouldn't be sole. Ha ha. Just kidding.
The real answer to your question is something called the Weak Anthropic Principle. It is easier, in terms of celestial mechanics, for habitable planets to form near solitary stars. The gravitational tides and perturbations in binary or multiple star systems make it harder for planets to exist in orbits that permit water to be liquid.

When the solar system was formed the result could have been two suns.
We would not be around,some planets and moons would also have formed but the configuration of the satellite system may have produced extreme conditions that may not have been conducive to life like ours.

Actually there billions of suns throughout the universe a star and a sun are the same.

Our sun (Sol) is a star: the nearest by far, but there are around 400,000,000,000 stars in our galaxy; the milky way. If there was more than one sun in our solar system, we would not be here.

actually there are millions of bilions of suns out there; we are just closest to this one :)
but the answer I think you're looking for is: we don't have more than one sun because our star isn't in a binary system so it is just there all by itself.

One sun is one system and our system is called SOL.

Can i ask u - Why there is only one You ?
Hope u are also one in this world.

who says u so? naah...theres not only one sun..there is one more ALPHA CENTAURI although it does not provides us with much sunlight its our next hope if our sun gets extinguished!!! there might b hundreds of suns that science have not yet discovered.....dont ask me..i dont know!!!
