Yes, and they've even recently found one that is possibly Earth-like. Unfortunately, they can't actually SEE the planet with a telescope. (it would be like spotting a christmas light taped to the side of a searchlight from the moon or further away than that).
What they do is measure a star's slight wobble to determine whether it has planets. You can read the article below for more information about this planet, or (as many have suggested) search for "exoplanets" to find a ton of information if you're really interested. Some sites are more boring and technical than others, but that's the fun of surfing around the web for info - finding the good stuff. :)

Absolutely, we have been aware of other planets for many years. They are Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune but apparently not Pluto.
They are probably many many more outside the solar system.
Your question implies that the earth is the only planet (I am sure you know it isn't) so you need to be more specific as the 'were' you mean as this changes the answer to the question.

Well, not any new ones in this solar system, the 8 here are pretty much it, except maybe for more giant snowballs outside of Pluto. But hundreds more have been found in other neighboring solar systems, and undoubtably, there is an average of probably 2-4 for every star in the sky. It hasn't been very long since we gained the capability to detect them - more are found practically every day.

There is a possibility that there is a livable planet out there but as we know it now there is nothing near enough for us to ever get there. It would be and impossibility that we would have a near chance to communicate.

They have found over 200 exoplanets already around over 160 other stars. And scientists believe we will find several Pluto-sized objects in the Kuiper Belt (we just don't have the technology to see such dim objects yet).

there is a huge number of planets in our galaxy waiting to be explored or even discovered so its not a very intelligent questions that u asked , of course there is astronomy is still a baby we need thousands of years to explore maybe 1% of the universe

"Out" where? In the galaxy there are probably lots of them. Around the sun, probably not, especially with the new definition of "planet"
