Cessna 152: root NACA 2412 tip NACA 0012
Cessna 172 Cutlass: root NACA 2412 tip NACA 2412 mod
Piper PA-28 Cherokee: NACA 65-415
Piper PA-34 Seneca: NACA 65-415
NACA report 824
gives
2412 Clmax (1.5-1.6) at about 16 degrees
64-415 Clmax (1.4-1.6) at 14-16 degrees
for a smooth, unflapped aerofoil, not accounting for 3D effects.
That looks fairly typical.
