Do you have any mohs values for these minerals to help narrow down what they could be? It's near essential for ID'ing specimens such as the first photo. If you don't have any mohs picks you can use other known minerals from your collection to perform a scratch test with... ie, if known mineral A (which is say quartz - 7 mohs) scratches the unknown mineral B, then we know B is 7 mohs or less. If it doesnt scratch it then B is over 7 mohs, and so on.
