- Atlantic City, NJ (pop. 39,558): ~62 miles SE of Center City, Philadelphia (Incorporated in 1854)

- Wilmington, DE (pop. 70,166): ~32 miles SW of Center City, Philadelphia (Settled in 1638, Incorporated in 1731, City Charter in 1832)

- Reading, PA (pop. 88,375): ~58 miles WNW of Center City, Philadelphia (Settled 1748, Incorporated in 1847)

I think Trenton would fall into the mix.

Camden doesn't really seem to be a "ring" city since it's right across the river. Reading is probably there, and Allentown/Lehigh Valley is likely getting there pretty soon. Calling Atlantic City a ring city of Philly is a major stretch though.
