I think that life will always appear when the correct chemical elements are available and the environment is not to hostile.
If you mean intelligent beings with which we could communicate I think there must be a vast number but the distances between groups are so large that no communication is possible on a human time scale

Life in Other Planet?

Yes both basic simple life forms like bacteria and much rarer intelligent life.  The problem is will we ever be able to detect this,  communicate with intelligent life or detect that intelligent life has existed.

My personal opinion is as follows

The detection of a planet with basic lifeforms.  we are quite likely to be able to detect that a planet has a high probability of basic  lifeforms like bacteria on it but it is unlikely that we will be able to prove positively that they exist without visiting that planet with some sort of probe.

it is very unlikely that human beings will develop the technology to visit planets on other solar systems although the possibility of a robot probe is not completely out of the question provided we have the will and extreme patience to wait what would probably be several hundred years for the results.

Intelligent lifeforms are vey much rarer and based on on local observations very likely to be short lived in the context of geological time so it is very unlikely that we will ever be able to achieve two way communication between any planets containing intelligent life.   However there is a reasonable probability that we will detect signals from another complex civilisation even if they are only its dying screams.

Most people just do not truly appreciate the distance between stars.  a round trip radio message to the nearest star takes eight years.  Our sun would not be visible to the naked eye more than around fifty light years away and almost all the bright stars are within one thousand light years and this is only a tiny part of our galaxy it is most likely that any intelligent life will be further away than this. meaning that round trip communication by radio will take more than two thousand years to achieve!  That is in effect right back to BC on our time scale.  On present showing it seems unlikely that complex civilisation will last another two thousand years without destroying itself with its excesses.  OK hunter gatherers will always survive but they are not interested in communicating with the stars!

The universe is so huge so it is impossible that except life on the Earth is no exist any planet with water.

yes and lots of it.
its everywhere. Even in giant molecular clouds.
