Calcite. I saw some emerald colored calcite wich looks similar to the green one. The other samples resemble calcite, but I am not sure. The emerald colored calcite would be rare. Calcite is soft, you should be able to mark it easily with a rock hammer or a pocketknife. If you streak test it, it will be a white streak, no matter what color the calcite is.

Yes, most likely calcite as it is the most common mineral with that crystal habit and cleavage. Though no way to definitively identify without testing.
