Probably too many to list. Both East Penn and Johnson control make just about every single group size battery for cars, everything from 24, 27. 47. 48. 51, 51R, 65, 75, 90, 94, 94R ect etc and both make commercial batteries in all the popular sizes. Both make RV and marine batteries as well.
With Napa they sell 3 different tiers all from East Penn. The Pro-former, the Legend and Legend Premium. They also have a AAA battery which is a premium with a different name. You are paying for the cold cranking amps and the warranty. The battery will have more or less plates in it or whatever it is to get you those cold cranking amps.
Walmart does the same thing and I know other parts store do the same thing. The cases on the most of these batteries is exactly the same but some store chains will have their own case style, I see them all the time because I've worked in parts sales for over 14 years part time. Really it's just the stickers on the batteries that change.
