This is kind of a question and a suggestion. could the fourth pic be a moss agate. Just looks to me as if the moss in the stone is imbedded in the stone also. Is that how moss agate gets it's name?
Also, the second pic looks like a cluster of quartz crystals but I am no expert. Can you take a pic of the other side of it? Also, apologies if I'm way off.

The chunk covered with crystals is quartz from Diamond Hill, SC. The rest of the chunks are all Savannah River Agate, which is actually chert. The Diamond Hill material comes out of the ground heavily iron stained and sometimes coated with manganese. The Savannah River Agate has been used for tools for about 15,000 years! I am not good at pictures but it tumbles GREAT! I ran a batch for almost 3 months in a rotary and the polish is unbelieveable! It is very tough to cut, set your slab saw at lowest feed rate possible. There are pockets of druzy crystals throughout the chunks as well as fossilized shells. Doug
