There are many, anything that has a hardness greater than 4 and less than 7, like Plagioclase.
Just listing the ones on the Mohs scale, there's apatite and orthoclase.

What mineral can scratch feldspar but not quartz?
There is no mineral that would satisfy the question. If a mineral is able to scratch feldspar, it would have a Mohs hardness of 6 or above. Fluorite is rated as a 4. It would be impossible for a mineral which scratches feldspar to be unable to scratch fluorite.
What can scratch fluorite?
quartz
Which minerals will not scratch quartz?
fluorite ,tale ,gypsum
Which minerals would scratch fluorite?
Any mineral with a hardness greater than that of fluorite which is 4 on the Mohs scale of hardness. Examples include quartz, orthoclase, garnet, diamond, etc.

Can quartz scratch corundum?
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
What mineral scratches fluorite?
the answer is something harder than fluorite some examples are granite , magnetite , diamonds , and quartz .
How can you tell if a mineral can scratch another mineral?
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
What minerals would scratch fluorite - talc quartz or calcite?
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
