Before I answer that question I want to explain something. The extra superspace dimensions encountered in supersymmetry are not like our dimensions at all. In theory they have no size at all and to an extent could be viewed as infinite points. They are different from the extra dimensions of string theory. Bosons and Fermions are two seperate projections of a single object-the string from String Theory or the membrane from M-Theory. Superspace is an intrinsically quantum theoretical construct. It may or may not actually exist as we tend to see it. Topology and or Geometry could through many combined examples duplicate its same effect. The test of such would be twofold:
1.) The theory is shown to explain things the Standard Model cannot.(To an extent that is already true.
2.) We prove superpartners exist.
Irespective of weither point 2 ever is proved if point 1 still holds then our construct remains a valid construct because like I said it may be simply that different geometries combine to produce an effect simular to there being a real superspace.

Mass,charge, and spin in one sence are not invariant. From a string perspective since one object can exist in two different forms and one has charge, yet, the other does not, then they are variable. But to the extent as already cited by others here they are invariant. It strickly depends on the point of view involved.
