The S valence would be -1 when Fe(II) is 2+.
In most cases sulfur has one negative and two possible positive valences: -2 and +4 or +6. So FeS2 is not a possible, or maybe a very rare, compound (Iron(II) persulfide?).

What does the 2 in the pyrite element FeS2 stand for?
FeS2 means 1 x Fe = 1 x iron 2 x S = 2 x sulphur. So there is one atom of iron and two atoms of sulphur in the molecule.

What is the valency of sulphur in SO3?
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
