No idea what these are

Digging around through some old things and found my childhood "rock collection".

Can't remember where I got any of these and have no idea what they are.

Originally thinking the translucent part of this was common opal.

This one is really sparkly, almost unreal.

Pretty sure this guy is bone but I have my doubts. Almost seems more rock-like

First one looks like chert, second one like micaceous schist and the third is petrified coral. That's my best WAG anyway.
