Laws of physics are not some fixed laws given to us by God. These are laws which our scientists have figured out by watching the world around us. What we have seen till today we have been able to explain by these laws but there might come a time when we will see something new in nature and will need to change laws of physics and those laws might make levitation an obvious phenomenon.

Yes, and no. Not in the conventional, Chris Angel type of way, but some European and Asian trains use a form of it. They use electromagnetism to keep the train a couple of inches above the track, and they never actually touch. This causes no friction whatsoever, enabling them to travel very fast. So with magnets, yes. In the Chris Angel type of levitation, no, it's just an illusion. A damn good illusion.

It depends on what you mean by the term levitation. Birds and airplanes do it all the time. We have countless ways to counteract the force of gravity. Unlike electromagnetic forces, we have found no way to insulate or shield against gravitational attraction. It doesn't mean it's impossible, but if it were possible, it's likely we would have found a way by now.

Define levitate.
There have been successful test of mag-lev (magnetic levitation) trains. The trains have powerful magnets that suspend the cars above the tracks and propel it along at incredible speeds.
If you are talking about anti-gravity, we do not even know what gravity is yet, so we cannot figure out how to oppose it.

It should be possible to defy gravity, even if it goes against the laws of physics. It might require a vacuum that reduces gravitational pull in a small area around your body, but it's still possible.

It is very likely that someone can levitate, you could focus energy at a weak spot in Earth's gravitational field causing a flux in the field around the planet, but that would be dangerous, because you would leave no way to protect from the sun's radiation, therefore killing us all. but if you could focus the "no gravity zone" in a containment field, and controlling it, it would be OK.

It depends on your weight. Your weight on earth is different to your weight on the moon since weight = mass*gravity. Your mass is constant.
Therefore on earth whose gravity is 10N/kg uou would never levetate. But on the moon or in a vacuum, you would be able to.

Not possible in my opinion, unless you have some futuristic shoes that help you defy gravity :]

All you have to do is to "flatten" the spacetime around you - then you´ll trick the Earth.
