Hardness is measured in three types viz., Moh's hardness, Brinnel hardness and Vicker' hardness.
Hardness of Iron is,
1) Moh's Hardness-4,
2) Brinnel Hardness-490 Mpa,
3) Vicker's Hardness-608 Mpa
Iron is not a mineral used in Moh's hardness scale.
The iron ore would be a rock composed of multiple minerals, each with their own hardness on the Mohs hardness scale. There are multiple ores of iron.
no, aluminum is softer.

It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
The hardness of glass is around 6, and the hardness of iron is about 5. So your mineral is probably around a 5.5.

It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
