The top photo is the "non-drive side" adjustable cup. Apparently you've removed the lockring and the holes in the cup use a pin spanner to remove it. You can improvise with a thin punch and hammer or even needle nose pliers. The cup has regular right-hand threading and comes out counterclockwise.
The lower photo is the "fixed cup" and requires a special wrench to remove or you can clamp the flats in a bench vise and use the frame as a lever. These cups are usually VERY tight and are left-hand threaded so they remove clockwise.
If you are just going to clean, relube and reassemble this bottom bracket and the cups are in good shape, it's not necessary to remove the fixed cup. If you are going to replace it entirely, then both cups must come out.
