x b). the cross product is where the right hand rule comes in. changing the charge to positive from negative just changes the sign of the force.
you have to specify which right hand rule you are asking about. there's more than one.
if you are asking if a charge moving through the magnet's field would experience a force in the direction of q(v×b), then yes, it would. charges don't care what created the magnetic field they interact with, just its strength and direction.
if you are asking if the metal would create a magnetic field in the direction determined from the right hand rule based on the "surface current" from the spins
