Not that anyone can say for sure but just based on the sheer number of stars, the chances seem very likely.

Currently, astronomers have been unable to detect earthlike planets revolving around nearby stars, yet have been able to detect large gas giants, some of which dwarf Jupiter. The reason being is that terrestrial planets, like earth, tend to be smaller and therefore harder to spot. Also, in order to be considered Earth-like, the planet would have to sit in an orbit around the star that allows a temperature range for the formation of liquid water. The distance of that orbit varies based upon the radiant output of the star, yet is usually a closer-in orbit than the planets we've discovered to date.
There are some projects that are planned for the next few years, that will have a greater chance of detecting Earth-like planets. I forget the name of the projects, however you can find the articles on Space.com.

If you're referring to a planet that looks like a big blue marble in space and be able to sustain life, well, not in our Solar System I'm afraid. But there might be planets in other Solar Systems that resemble our Earth although I'm not sure whether we'll ever manage to confirm their full status given the vast distances between our Earth and these Solar Systems. Currently, we can confirm planets the size of Jupiter only.

If you are asking based on something having the same size as Earth? Yes
Something with an atmospehere? Yes
Venus and Mars are an easy answer to both questions.
You also have Titan.
As for if a planet supports life?
Bacteria grows just about anywhere.
More complex life forms can grow on just about any mix of atmosphere, gravity, liquid water.

That's the huge question astronomers, NASA, and everyone on Earth wants answered!

No there ain't, but.... There is a moon called triton, its one of saturns moons and the atmosphere is not as thick but is close and it scientists say that they think it has water, oxygen, and all it needs is a thicker atmospher and it might be able to sustain life, any questions let me know ok.
