Can someone help me understand what are these minerals and if they are dangerous?

The red one and blue one are man created and probably not natural although the blue one might be a post mining color enhanced chalcanthite. The purple one in the middle is a small piece of amethyst variety of quartz. As there are so many localities for amethyst, no specific locality can be given for a small generic piece.

None of the minerals are dangerous unless thrown at someone else's head or eaten for a snack. BOB

I would add that the one on the right appears to be lab/ home grown copper sulfate and is toxic. I had my chemistry students grow these and more.

The blue one is, as others have stated, lab-grown copper sulphate crystals, and only harmful if you eat it. But it tastes sooooooooo bad, that no one will eat it. If some child puts even a tiny grain of it in their mouth, they would be immediately furiously spitting it out, with no further harm. But keep it away from toddlers anyway.
