If you could give us an idea of what part of the world these rocks came from, that would help.

First one looks like a quartzite pebble that split open; second one is hard to see but maybe a chert of some type, last one is a small tigers eye sphere / marble (tigers eye is a also a type of quartzite). So they are probably all mostly SiO2 is one arrangement or the other.

I see crinoid fossils in the second one so it's limestone or chert. Gary
