Hexane is the least polar solvent so it would separat the least polar compound,
70/30 (hexane/ethyl acetate) is used to separate an average polar compound.
95/5 (CH2Cl2/ MeOH) is used to separate the most polar compound.
Note: Since the structure for the 3 ferrocenes are not given, so cannot predict which solvent system would separate which ferrocene.
