Among Cu Pb Fe Ag Al Mg Zn it is magnesium will corrode more because it is more reactive than the metals listed.
Zinc (Zn) does not have variable valency
When your paper clip is made of (or coated with) more reactive metals than copper, like Fe, Zn or Sn, it might react with Cu2+ ions in your solution. Cu2+ + Fe(s) --> Cu(s) + Fe2+
Zn
H2
Mg, Mn, Co, Ca, Cd, Fe, Zn, Se

Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.

Zn
YES METALS DISPLACES HYDROGEN FROM ACID FOR EX- Zn+H2SO4----->ZnSO4 + H2
The elements that are in group 2 of the Periodic Table, namely Be, Mg, Ca, Sr, Ba and Ra. Some other transition metals will form +2 ions, such as Cu, Zn, Fe, etc.
No, Zn is less reactive than Mg
