I'm talking Solar Sytem planets and moons here.
Europa ties with Mars; liquid water ocean under her ice crust, organics and an energy source (geothermal). We should be looking a lot closer at Europa... but Mars is much easier to get to. Next I would say Enceladus, a tiny moon of Saturn, which also has the 3 requirements... probably. Ganymede and Callisto have oceans 100 miles under the ice crust surface... but what energy sources?
A long shot would be Titan although its pretty cold there; it would have to be "life as we don't know it" and use something else besides water as a liquid solvent. The dark horses would be Venus (in the clouds 50 miles up) and Io which has a lot of energy sources; again life as we don't know it.
And there is always the Jovian planets which have huge atmospheres with clouds that have Earth-like conditions of temperature and pressure.. but can life form in a gas or does it need a liquid (ocean)? I suspect life is pretty much everywhere there is (1) liquid water (2) organic carbon-based chemistry happening (food) and (3) an energy source life can utilize for metabolism.

It is not likely there is one in our solar system besides earth.
But there are,no doubt, millions or billions of planets through out the universe that could support life like ours.
Any alien life would be based on some type of DNA which would make it the most likely candidate for carbon based life.

As far as we can tell for sure ... none. But statistically if there other planets around other stars (and we have proof of them now), then some planets must be the correct distance (to support life as we know it). Some one did a calculation which was very conservative and due to the number of stars in our galaxy (lots and lots!) the number of habitable planets came into the tens of thousands or more! It's just a matter of time before be 'hear' their radio signals. Maybe not in our life time or even a hundred lifetimes, but someday.

Well... There aint a planet but there is a moon that is possible. Titan is one of saturns moons, they say that there maybe lakes by the north pole in reasent studies, It has an atmosphere but it is not as thick but it is said to have oxygen, water, and other stuff, so The answer to your questian is no , because you said planet, but it is yes for a moon to support carben based life forms.

We have no idea. We've only found less than 100 planets and don't have enough info on the yet. Out of the trillions out there, that's a pretty small number.

I agree with Gnomon - as far as we are currently aware no other planet could support C based life.
Even if another planet in our solar system could - it would take a fair while to get there, providing you could get through that dodgy asteroid belt just between Mars and Jupiter........
