Yes, some. Though gold is a soft element it is not the softest
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
No, minerals and common objects with the same hardness are not able to scratch each other and leave a mark behind. For example, minerals with a hardness of 2.5 - 3 include gold and silver. Try scratching two pieces of jewellery made of gold and silver. It does not make a mark at all!
The human fingernail can just scratch gypsum, but is softer than all other minerals.
yes.
All of them
minerals don't break other minerals yet they can scratch other minerals based on their hardness which is measured by the Mohs scale

Diamond
yes.

See if your finger can scratch the gold. If your finger nail can than you have pure gold. But because gold is weak like that the jewelry stores usually put other minerals to make it harder.
