The cations are Ca ++ , Fe +++ , K +
The anions are Cl - , SO2 -- , SO4 --
So, following compounds can be made from the given cations and anions,
CaSO4 (calcium sulphate)
CaSO2 (calcium hyposulphite)
CaCl2 (calcium chloride)
FeCl3 (ferric chloride)
Fe2(SO4)3 (ferric sulphate)
Fe2(SO2)3 (ferric hyposulphite)
KCl (potassium chloride)
K2SO4 (potassium sulphate)
K2SO2 (potassium hyposulphite)
Hope it helps!

Compounds are formed by the combination of cation and anion.
On combining all the possible positive ions with negative ions, we get
CuCl2,CuSO4,NaCl,Na2SO4,FeCl3,Fe2 (SO4)3
