Need help identifying baseboard cap profile

The "three stairs" could be cut with a straight bit or saw (and a fence, set over multiple times) unless you are running enough linear feet to justify a custom-ground shaper bit. I'd just call them rabbets.

The part above that feels like some flavor of ogee moulding from the picture (less so from the drawing, which looks closer to a quarter round.)

Millwork shops typically charge $100 to $500 to make custom shaper knives to match your profile. Alternatively, any cnc router can make any custom shape like that. Lastly, if you wish to, you can make a home made plaster molding to match using this technique:

Some of these mouldings can be recreated by multiple router bits -- your run the top half through one router bit and the bottom half through another router bit.

Bottom could be made by a triple bead router head, and the other half is a fairly standard profile -- possibly a cove, but hard to determine from your picture.

Going to a specialty woodworking store that sells router bits and has a dedicated salesperson might be worthwhile.
