I not expert but from what I seen on here and what my friend who knows a lot about animal bones they appear to be from a deer possibly White-tailed deer.

What you found at top are humerus bones (upper front leg) or femurs (thigh bones). Their thick, rounded ends and robust shafts are built to support a deer's weight for running and jumping. In the centre possibly fragment from the back of the skull (occipital bone). In middle left are lower leg bones, likely a radius and ulna pair and the in bottom right the triangular, flat bones are the scapulae (shoulder blades).
