There would be no metal-to-metal friction as in the case of a conventional bearing. There will be friction of the rotating component moving through the air. There will also be resistance of the magnetic field passing through the moving parts. This is called magnetic hysteresis. Both will cause a loss of energy at a rate proportional the the speed of the moving part.

You mean a bearing held in place by magnetic fields? By avoiding contact, you will reduce friction but total elimination of friction is not possible. You cannot create a perfect vacuum.

Yes, apart from the fluid dynamics in the interspace.
