I’m not an expert but the second image looks like a deer pelvis, so if the others were found close by it then the rest could be deer bones. Not sure though.
1) femur: the ball of the ball and socket joint is at the upper left. That nettles into the round socket in the second photo.
2) pelvic girdle, which consists of three fused bones; the bowl-like dip you can see along the lower left side, midway, is the acetabulum, the socket of the hip ball-and -socket joint.
3) a vertebra, possibly from the neck, but I can’t tell from this angle, although the presence near the other bones makes me think it’s probably from the lumbar region of the spine (the part of the back between the hips and the rib cage).
4) one of the sacral vertebrae, which are unusual among the bones of the spine in that they are fused to one another (and so are not flexible) and to the pelvic girdle (picture #2), and have come un-fused as the connective tissue rotted away. These are fused to provide better strength to the hind quarters, which allow greater speed (the front limbs are support, not speed, rear limbs do both).
