In the near future the Sun will start to grow and Earth will start to die. As the Sun grows the habitable zone will move further outwards. Mars's polar ice caps will start to melt and cover the planet with liquid water as Earth's water evaporates.
If we have the technology when this happens we will be able to travel to Mars and live there until the habitable zone leaves Mars. After that happens we will have to live on asteroids and other moons. Almost all the inner planets will incinerate then the Sun will shrink and grow and shrink again until the Sun's core collapses and explodes.
So the closest habitable planet will be Mars which is 50 million miles away.
It takes 77,000 years and longer than a life time to get to our nearest planet or (solar system).
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
If you mean, which planet could we just open the doors, plant a few vegetables and get on with life, then none - so far. Mars could be habituated but not without problems. No air or soil would be a major problem. At first everything would have to under domes, somehow protected against meteor strikes.

It cannot, a star can only have one or no habitable zone. Actually, many stars in the universe have none (or very, very inferior ones.) There are various reasons; one of them being that most stars exist in groups of two or more, making it difficult for a planet to have a stable orbit with just the right amount of constant starlight to be habitable.

second nearest planet to sun. Example: Venus is not habitable!

It is impossible to survive on the planet Neptune. This planet is very far away from the sun and therefore is very cold and not habitable.

As of (2011) no planets have been observed that are habitable. Some MIGHT be, but until detailed research is done on the actual conditions, it cannot be said a planet is habitable.
earth..The most habitable planet in the Solar System is Earth. As of June 2014, Earth is the only planet that has sustained known living things.
Terraform it.

None that are known. There may be a roughly Earth-sized planet in orbit around Alpha Centauri B, but this planet, if it exists, would be far too hot to support life.
