There are so many ways to use crystals. I carry them with me in a pouch every day, about 3 with clear quartz & a piece of selenite. I use them in spells, my wand is made up of crystals, there are so many uses for them. You can even just collect them to have them. It’s really up to you.
That is a good start though, you could make crystal grids or use them in meditation.
@Missa or @Christina4 is much better at identifying from pictures than I am, but I see the selenite, amethyst, & rose quartz.

I wish knew what the others were so I could find some information for you.
