Would you consider these more or less processed than butter, yoghurt, cheese, peanut butter, pickles, or chocolate? Why?

The same or similar. Well, chocolate is probably more. The point OP is trying to make is that yogurt has most of the stuff found in milk( different yogurts vary of course). But e.g. eating greek yogurt is way better than whey isolate.
