Nice finds ! Looks like mostly malachite to me , but i think there are some with azurite , and some of the more saturated blues stones may be turquoise - close ups ,and posting in the rock forum will help you.

Looks like chrysocolla a greenish-blue mineral consisting of hydrated copper silicate, typically occurring as opaline crusts and masses.
