Carl Edward Sagan, famous astronomer, once said "How arrogant we are to think that we are the only living beings in the universe!" There are, no doubt, an unlimited number of inhabitable planets out there, many with original inhabitants. They may be millions or billions of light years away, but no matter how far you go, you can always go that much further.

No planets that have so far been discovered either inside or outside this solar system are inhabitable apart from Earth.
The closest is to being inhabitable is Mars and it is very chilly and has no free oxygen in a very thin atmosphere. But it does have a thin atmosphere and there is water in the form of ice. The day is less than an hour longer than that of Earth and the axial tilt is similar. In the reasonably close future people will be living on Mars, possibly partly underground. See the "Mars Society" websites and Robert Zubrin's "The Case for Mars".

(Habitual = Inhabited)
Earth is not the only place in the universe where there is life. It's an awfully big universe to not have any more life in it then just one small planet off in an isolated corner. It would be like building something the size of New York City for one tiny flea.

So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.
Why haven't we heard from them?
Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.
Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.
Perhaps they are so far away they will never notice us and vice versa.
Perhaps they existed a million years ago and died out.
Perhaps they will exist a million years from now.
It is really impossible to know for sure.
The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

I think you mean "habitable" not habitual. Habitual means a habit, like smoking or biting your nails. "Habitable" means it has a 'habitat', an environment in which living is possible. Me personally, no, I don't believe that. If there were, we'd have been contacted a very long time ago. If any other more intelligent race is out there, they would have contacted us. I do not believe they would NOT contact us because we 'are not ready'. If they are so smart, they'd be able to deal with us as we are, not as we need to be at some future date when we are more evolved.

Yes, I believe that Earth is not the only inhabited planet.

No, I don't. The Universe is vast, so in all probability there are other Earth-like worlds out there with creatures living on them. How rare or common they are is one of the greatest mysteries of the universe. I would be amazed if they find another Earth within 50 light years, but you never know.

Assuming you mean habitable, then yes, I believe that somewhere in the cosmos, there is another planet that can support life. Whether there is life there or not, and what form it may take, I do not know.

it's possible but i have little evidence either way. we know there aren't any near by and the closest other star is a ridiculous distance away, 21 light years or something, so even at light speed it's still a 21 yr trip. i think
