Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Halite, which is the mineral name for salt, has a cubic crystal system. Therefore, another mineral with a cubic crystal system would be pyrite.
No. Because of the confusion between turpentine, mineral turpentine, mineral spirits and mineral oil, I have included links to all of these substances. All of the above except mineral oil are toxic if one drinks them. Turpentine is the only one that is not a petroleum distillate. Mineral oil as sold in a pharmacy is for constipation and to be used as directed. See related links.
The color of a mineral's streak is always the same, hence diagnostic, whereas the color of a mineral can be highly variable.
no not at all

Absolutely. For example, Galena and Halite.
You start by scratching it and seek it's hardness. When you find its hardness, compare it to another mineral with the same hardness. If they look exactly the same, and have the same arrangements of minerals, then they are the exact same mineral.

Yes, all different samples of that mineral will have the same cleavage.

They are said to be congruent with one another
no they are not the same type of mineral.

They are the same mineral: carbon. The difference is in their molecular architecture.

If a triangle has the same 3 sides and the same 3 angles as another triangle then they are said to be congruent.
