Yes, those are definately Corals, both colonial and solitary, a brachiopod in the center, and what looks like a section of a crinoid stem on the left of the bottom photo (have a closer look at that stem and see if maybe it is cephalopodish). The top photo looks like it has bryozoans on it, kinda hard to see.
The third photo below does have symetry to it, alot of concretions are symetrical too. It looks like a echinoid but I still think (without a good close examination) it is a concretion.
At first look, it looks like a good Paleozoic, possibly Carboniferous, fossil locality. Keep looking and keep posting and good luck.
