Picture 1 Crinoid stem fossil thats been agatized much like petrified wood.
Picture 2 What I'll call sugar quartz, small quartz crystals in a vuggy lattice.
Picture 5 A quartz vug with large crystals. Picture 6 Another quartz vug from a seam of quartz. And picture 9 The same as the last one.
Pic 11 What I'll simply call quartzite, a dense quartz materiel though this one looks like it was found in a stream.
Pic 3 Looks to be a sedimentary stone with a high silicate. Would polish up nice.
And the last two The same for this too however I appears to be fossilized mud.
Pic 4 This one could be chalcedony but it has the look of something formed in a cave. Hardness test would help.
As to the rest, stones

Cant really say much more than that.
My opinion.
