normally, a 747 flies about 500 knots, or 580 mph, at about 33,000 ft. depending on the weight, it normally flies between FL290 and FL410. it is certified for 45,100'. (the speed doesn't change that much with altitude or weight -- it usually is a function of trying to save fuel)

Yes, of course!
The same way any other airplane flies. Airplanes have lifting surfaces - the wings and the tail. The faster you move air past them, the more lift you get. A 747-400ER has a maximum takeoff weight of 910,000 pounds; if you move the plane fast enough to generate enough lift to counteract that much weight, it will fly.
