Irons
diamagnetic material
The most common ones are iron, nickel and cobalt, though there is a great variety of somewhat exotic ferromagnetic substances.

francium.
Nickel is a ferromagnetic material and magnetic. So, German silver (called also: nickel silver, argentan) is magnetic.
Yes, steel is a ferromagnetic material.
Probably not. You need a ferromagnetic material for a magnet to stick. There are basically three elements that are ferromagnetic: Cobalt [Co]; Nickel [Ni]; & Iron [Fe] (and some esoteric ones too). If the metal alloy that has been plated with silver to make the "silver plate" has enough of these then a magnet will stick, of these, only Nickel is commonly a component of alloys that are plated but often not in concentrations that are sufficient to make it obviously magnetic.
No..magnets are only attracted to ferrous (iron) materials.
Neither lead nor silver is ferromagnetic. It's possible that some magnets may contain small amounts of lead and/or silver as contaminants, but as far as I know there are no common magnetic alloys that involve either of them in significant quantities.
no
No. Gold is diamagnetic. The only ferromagnetic metals at room temperature are iron, cobalt and nickel
Because most refrigerators are made of ferromagnetic materials, and ferromagnetic materials are attracted to magnets.
