If by 'us' you mean all humans, then by definition no. If you mean by us here on Earth then it depends how you think we got here and if you believe in evolution and what you mean by the universe.
The probability of two independent evolutionary tracts producing the same end product is very very low, even if they start from the same building blocks. Even the probability of independent 'humanoid' life forms is very very low. However if the universe is infinite and homogeneous then yes, there will be an infinite number of worlds with humans. Its just very very very low probability we will ever find them.
If you want to believe in a creationist theory then its different. If some external force created humans here then maybe it used the same model elsewhere (although most creationists theories are wrapped up in a biblical idea of uniqueness of this world so don't support that view).
As conventional scientific thinking is that the universe is finite and evolution does occur, the conventional scientific view is then no, the probability is very close to zero.

There is no chance of there being any other human beings in the universe exept us! Because everything else in the universe isn't human!

As a Creationist, I'll note that the Bible only says that God created man and earth and everything, it doesn't say anywhere that He did NOT create more humans somewhere else in the universe, and the universe is MORE than big enough for God to "hide" them out there somewhere. We won't possibly know until we meet Him personally.
From a non-Creationist point of view, it's equally impossible to ever be sure. The circumstances needed for a planet that supports life as we know it are nearly impossible to occur naturally. But since apparently out planet exists, in an infinite universe there must be other instances similar to ours. (although certainly not in our galaxy).
One thing is for damn sure either way. If there IS other life in the universe, we sure won't ever cross paths with them.

There can be no other human beings in the universe, because Earth is the only place where they can be found. Other life, however, is pretty certainly out there.
In our galaxy alone there are over 4 billion stars, each one a sun. Not all are the same as our sun, but the majority of them can support planets. There are millions of other galaxies spread across the universe. To say that we are the only piece of rock capable of supporting life seems a tad silly to me :-).

Dear friend, I agree with the astrophysic CARL SAGAN, logically is impossible, matematically impossible, and astronomically impossible, that we are alone in the universe, but even with the recent discovery of the planet equal to our plantet.

We are not alone. Extremely probable we are the only Humans though.

Probably not. But there are almost certainly other intelligent life forms out there.

I do believe there are other lifeforms somewhere in this huge universe. We may never discover them but they may have discovered us!

I don't think so...
But, maybe there's any species somewhere in this universe.
We only never find it yet, but I think someday, we'll know about it.
