Explanation / Answer

Will displace H2 from water :  Na (Sodium is very reactive and reacts vigorously with water)

Will displace H2 from steam or acid, but not water : Mg (reacts with steam or acid)

Will displace H2 from acid only : Pb ( Does not react with water in any form)

Will be displaced from an aqueous solution of its cation by Pb :  Ag (Pb is more reactive than Ag only among given metals, so it can displace Ag from its aqueous solution)
