These Brachiopods are Pennsylvanian in age, central Arkansas.

I've numbered your items to make them easier to discuss. 

# 5 looks like a bivalve, not a brachiopod.

 

Any idea on what Formations these were found in?

 

Some of these may be too partial to ID confidently.

I was unsure of #5 was thinking it looked a bit scallopy…lol. Boone formation Mississippian and atoka formation Pennsylvanian.

3 is a mucrospurifer

You must have found some devonian because mucrospurifer went extinct before pennsylvanian

Not necessarily Mucrospirifer. Could be any number of spiriferid brachiopods.
