The topic of life on Mars has been one of hot debate lately with the recent Rover bot finding more "possible" signs of life on Mars. However, there is no definitive evidence that there is life on Mars.

Yes. it is possible that there is life on any or every planet, satellite, etc. out there. it just hasn't been proven that there is or isn't life on Mars, or any planetary object for that matter.
As far as we know there is no life of any kind on Mars.
no, at least not that there is any evidence of them. so at the moment no, but there are signs of water on mars which points to chances of living organisms.
no water, weak greenhouse effect (if any, don't remember), too cold.
There is no evidence of any form of life on Mars. Scientists are exploring the possibility of past microbial life on Mars, but as of now, there is no definitive proof of any life forms existing on the planet.
If you were to just put a person on Mars, then no. There is no oxygen on Mars, and oxygen is essential to human life. However, if there were buildings which could provide the oxygen, similar to a space station, and there is plenty of food, then yes it is possible for a human to survive on Mars.
There are no animals on Mars. It is void of any life.
