Homogeneous
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
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.
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
The color of a mineral can vary depending on impurities present in the crystal structure. So, two minerals of the same color may not necessarily be the same mineral. Therefore, relying solely on color as a identification test can lead to misidentification of minerals.
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.

They are said to be congruent with one another
Yes, all different samples of that mineral will have the same cleavage.

no they are not the same type of mineral.

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

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