Yes magnatite does and it can be scratched by a nail Jk!
yes.
I would say not likely. Most metals are rather soft in their pure form. One of the most distinguishing characteristics about metals is that they are sectile, or easily cut with a knife. Silver has a hardness (on the Mohs scale) of 3. That is probably not going to scratch many other minerals.
Yes. Barite is able to scratch any other mineral, or rock composed of minerals, with an equivalent or lower Mohs hardness rating (Barite: Mohs 3-3.5).
Feldspars, biotite, magnetite, and quartz are found in varying degrees in igneous andesitic rocks.
Some minerals have varying hardness according to the direction you may scratch

Diamond will scratch all rocks and other minerals, including itself.
Ferrogeneous Rocks. Eg Magnetite and Ironstone.

Minerals commonly present within skarn rocks include garnet, magnetite and epidote.

The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.
Magnetite is created through sedimentary rocks. They are also formed by metamorphic rocks. Magnetite is found in underground mining regions.
