There are two different way to measure an airplane's speed: air speed and ground speed. Air speed is measure of speed relative to the air. Ground speed is measure of speed of airplane relative to the ground. these can be two differenet values if the plane has a low enough flight speed and there is a strong enough head wind. It is even technically possible for an airplane to fly backwards in sever headwinds. If the wind going over the wings is enough to create lift for the airplane it will fly--regardless of how fast relative to the ground it is moving or not moving.

Yes it can, and I have see quite a few jetliners apparently hanging in the air.
The pilots achieve this by adjusting so that the thrust is just about enough to keep the plane in the air but not moving forward at a great speed.

yes, very possible. It is called "hovering" many of today's helicopters and newer aircraft's are able to do just that...

yes only if its weight is less and its thrust is maintained constant
