Diamagnetic substances are not magnetised. Example: water is a diamagnetic substance, so it cannot be magnetised by any means.
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
No.

Not usually, but it can be magnetised. (=
Iron is naturally magnetized.
