Your fossils look a lot like the Ordovician limestone from southwest Ohio, 500 million years old. I've got a chunk of that somewhere around here with a starfish amongst brachiopods. The round disk things are crinoid stems. I'm not sure if the fan things are part of the crinoids or some sort of coral. There are fossil fish to be found in the Devonian age shales along the river banks around Cleveland, though I have yet to find one.
