First is MI Puddingstone. The others look like Quartz/Agate from MI.

Thank you for that. I'm so excited that those are my first! And so, are quartz and agate the same then?

Not the same. Agates may contain quartz. Plain quartz has no banding like agates do.

Quartz & Agate: Now you've done gone and done it maggie ! I aught to write a book about this. It takes many forms! (Polymorphs) Silicon is the 6th most common element in the universe, easily combines with oxygen to become SiO2, the inverse twin of H2O - water ! SiO2 is not very soluble, but SHOCK WAVES shatter silica bonds and groundwater greedily grab onto those bonds to become silica gel. Most AGATE is formed during the shockwaves of impacts, continental collisions, volcanic explosions and earth quakes! Fire Agate!
