Hey Beef! I won't pretend to be a mineral expert and I'm sure someone will do better than I but I'd say A. Dogtooth Calcite B. some kind of tourmaline c. Left covellite rt. strictly a guess but maybe bornite or some kind of goethite pseudomorph ( lots of man created iridescent metallic minerals too) D. Looks like mimetite and E. maybe fluorite F. Dunno *S*.....Mel

Dang, I've seen every one of those before but, like Mel, I also am not much of a mineral-specimen type. But I agree with his IDs as well. My best guesses are:
A) Seen it but don't recall. B) Tourmaline C) at first I thought chalcopyrite (peacock ore) but yours is too crystalized. D) wavelite?? E) Flourite, or maybe a psuedormorph after pyrite? F) dunno
Because I'm certain I've seen them at shows, I bet you could find a local mineral person to ID them all.

A. Calcite. B. Tourmaline or epidote C. Hematite on left, carborundum on right D. Wavellite E. Pyrite, marcasite or galena? Need better pic or details. Looks metallic, how heavy is it? F. Mimetite. Need better pic or details.

A) Calcite, Mexico B) a tourmaline group member, probably elbaite, probably Brazilian C) both are carborundum, a manmade abrasive D) wavellite from Arkansas. Nice piece, normally you see flat sprays instead of complete balls, which require open space to grow. A keeper if good green and not too much damage. E) if purple is present, with a thin black coating, it's a fluorite, probably Illinois F) the left piece looks like calcite colored by conichalcite. The two on the right are ADAMITE and will fluoresce brightly in SW ultraviolet light. All from Mexico.
Typical rockshop material, readily identifiable, so I'm very sure of the identities.
