Hi,

I've looked at your picture, and I am afraid it is too far away to make anything like more than a guess.

Can you photograph each one individually so that any structure or crystal shape shows up.

If it is needed, I suggest you dust them first (with a dry paintbrush), but don't wet them.  Firstly, a picture of a specimen wet does not enharnce it, and secondly one of then (I am fairly sure) may disolve in hot water.

John if you guess!

please

If that is how you want it thats fine.

The best I can do - (reading left to right top row ).

Calcite    /    ?    /  garnet  /   gypsum   /  kyanite

I am unable to even guess at any on the bottom row.  They are simply not good enough photos

No idea here either, at least try and improve the lighting or not upload a screenshot of a photo from a computer?

Better images = better conclusion, also a short description of the stones would help. 

I have created this short guide, hope it helps.

Rocks & Minerals Identification Tips.

When asking for help with identifying rocks and minerals the more information you provide will allow better and more precise conclusions.

PHOTO 

The specimen should be clear. Use the macros feature on your camera for small specimens. If your camera does not have a macro option then keep the camera at least 50-70 cm from the specimen. If the size of the specimen in the image is then too small, trim the photo and upload the trimmed photo. Use day light if you can so that you get good color, and if you cannot use a low power day light bulb, Use a tripod or something else to keep it stable. To avoid reflection from the flash try putting tissue paper over the flash 

LOCALITY

Where was the stone/mineral found, this will help determine by referencing previous finds and or local geological knowledge.

COLOR

Try to describe it as best as you can by referring to other rocks or other everyday items. On many occasions the color of the photo will not be accurate so the color of the mineral will not be correct – so tell us the color you can see in day light. 

LUSTER & TEXTURE

Its possibly the hardest for those starting out in the hobby: it is best to check this using daylight, to say that it is ‘metallic’ is easy, ‘semi-metallic’ a bit harder and then ‘non-metallic’ easy again: In the latter you can add other descriptions such as ‘silky’ (fibrous gypsum), ‘glassy’ (quartz), ‘greasy’, ‘waxy’ (talc), and ‘resinous’ (sphalerite).
