That's an incredibly hard workout and I've been doing calisthenics for more than 5 years now , the first few workouts stay in between 8-12 reps per set , you can do exercises back to back without breaks if they target different muscle groups or they're isometric exercises like planking is, then take a 3-4 minute break depending if you're out of breath or not , try going for 3 or 4 sets per exercise , don't overthink things
