Mix of possible and odd fossils

[Dino2033]

I have these finds that I would like some assistance on deciding what they are. Two of them I am unsure that they are even fossils while the third may be a sphenopterid but I am unsure. Thank you all for your help! Carboniferous of Rhode Island. Scale is in cm.

Also I would like to add this fossil from Cory’s lane (same formation). There is one part that may be Odontopteris but I do not know what is above it.
