Solution

Magnesium will replace metals from Copper sulfate, Zinc sulfate, and Iron sulfate.
$M g + {C u S O}_{4} ⟶ M g {S O}_{4} + C u$
$M g + Z n S O_{4} ⟶ M g S O_{4} + Z n$
$M g + F e S O_{4} ⟶ M g S O_{4} + F e$
$M g + K_{2} S O_{4} ⟶ N o R e a c t i o n$
$M g + M g S O_{4} ⟶ N o R e a c t i o n$
$M g$ + $C u S O_{4}$ $⟶$ $M g S O_{4}$ + $C u$

Zinc will replace metals from Copper sulfate and Iron sulfate.
$Z n + C u S O_{4} ⟶ Z n S O_{4} + C u$
$Z n + F e S O_{4} ⟶ Z n S O_{4} + F e$
$Z n + M g S O_{4} ⟶ N o R e a c t i o n$
$Z n + Z n S O_{4} ⟶ N o R e a c t i o n$
$Z n + K_{2} S O_{4} ⟶ N o R e a c t i o n$

Copper is less reactive and will not replace metals from their solution.
$C u + C u S O_{4} ⟶ N o R e a c t i o n$
$C u + F e S O_{4} ⟶ N o R e a c t i o n$
$C u + M g S O_{4} ⟶ N o R e a c t i o n$
$C u + Z n S O_{4} ⟶ N o R e a c t i o n$
$C u + K_{2} S O_{4} ⟶ N o R e a c t i o n$

Iron will replace Copper sulfate solution.
$F e + C u S O_{4} ⟶ F e S O_{4} + C u$
$F e + F e S O_{4} ⟶ N o R e a c t i o n$
$F e + M g S O_{4} ⟶ N o R e a c t i o n$
$F e + Z n S O_{4} ⟶ N o R e a c t i o n$
$F e + K_{2} S O_{4} ⟶ N o R e a c t i o n$

Potassium is the most reactive and will replace all metals from their solution
$2 K + C u S O_{4} ⟶ K_{2} S O_{4} + C u$
$2 K + M g S O_{4} ⟶ K_{2} S O_{4} + M g$
$2 K + Z n S O_{4} ⟶ K_{2} S O_{4} + Z n$
$2 K + F e S O_{4} ⟶ K_{2} S O_{4} + F e$
$2 K + K_{2} S O_{4} ⟶ N o R e a c t i o n$
