    Two things:
    1. Your photos have not been correctly embedded. All I see are fourteen copies of an advertisement.
    2. This looks very much like homework. On this forum we are happy to help you with your homework, but we will not do it for you. You need to show us that you have tried to identify the rocks/minerals.

    Welcome to the forum.

    OK, in that case I'll be pleased to try to help, although I confess I am not very good at doing identification from photos. I'm still not seeing the actual photos. You may need to re-upload.

    those numbers are the one on the container

    5 probably is schist
    7 Halite?
    8 olivine
    12 the pink colour i think is orthoclase
    13 tourmaline
    14 conglomerate

    14 Yes. It is conglomerate. If the pebbles where angular would call it a breccia.
    13 I'm not very good on minerals - tourmaline is possible.
    12 Orthoclase is a reasonable estimate. This could be a pegmatite vein.
    2 This seems to be a mix of feldspars (white) and ferromagnesians (dark), so I'm guessing a gabbro or similar.
    5.Schist? Either that or interbedded sand/shale. You can handle the specimen so I would trust your suggestion more.
    7. I think it is certainly an evaporite, but I'm not sure about halite. My first thought was gypsum.

    I'll try to get back later to look at the rest.
