I think it is probable that SOME form of life exists on these planets, but without knowing the probability that life will begin at all, it is hard to say.

As for intelligent life, i.e., capable of civilization and technology, I think that is quite rare.  After all, it took 4 billion years for it to develop here on Earth, and the Earth has a lot of lucky advantages, such as a large moon to stabilize its motion, to create tides (making evolution from sea to land creatures easier), large outer planets to shield the Earth from many large comets and meteorites, etc.

But there are thousands of planets like Earth. Many of them are not yet discovered. In order to reach them, we have to travel in the light speed.

We may not have to travel to these planets to see signatures of life. With more sensitive observational instruments, we may be able to see seasonal variations in CO2 and O2, as on Earth, variations in vegetation, etc.

And of course, we will still be listening with SETI.  :)

Maybe they are watching us too :D (or) Life may be just is bacterial or animal form in other planets.

There might be forms of life on certain "habitable" exo-planets, but at which stade?

Yes

It is possible that life exists on other planets.

'Life' in the strictest sense? Maybe.  

Multicellular intelligent life? Not really, no. 

If you look at the Drake equation its hard not to say yes. The numbers pointing in the favor of life in the habitable zone are staggering.
