iron, steel and other metals that contain iron
All iron or steel (even stainless steel) is ferrous. The word "ferrous" means "iron." All steel contains iron. All steels also contain impurities which improve various useful properties of iron, such as strength. There is high carbon steel, or steel with chromium or other elements that improve abrasion resistance or reduce rusting (stainless steel). There are some non magnetic steels, but because they contain iron they are still ferrous.
Yes. As far as I know, staples are made of steel which contains iron.
It depends on the can. Soup cans might contain steel. Soda cans are made of aluminum.

A non-ferrous metal is a metal which doesn't contain carbon. Mild steel does contain carbon. So mild steel is a ferous metal. Mild steel is NOT a non ferous metal
