From the research that I have read, the length of your break has no influence on hypertrophy. The best indicator of hypertrophy is either volume, as in tonnage (sets times reps times weight) increasing over time, or more recently the number of "hard" sets per workout, meaning the number of sets which leave you close to technical failure (not at failure or past failure, just close to it). Doing exercises one by one gives you more time to recover and go harder on the next sets (meaning you can do a greater volume on hard sets), which is thus more optimal for hypertrophy.
All that being said, what you are doing right now is called supersets/multisets and it can be ok to some extent to save time. For example, I frequently superset antagonistic movements (bench press with dumbbell rows, overhead press with chin-ups, etc.) because they don't really influence each other, but I always keep at least one of them light. I wouldn't recommend doing more than 3 exercises though, and no more than 1 heavy compound lift at a time (squat, bench, deadlift, overhead press, barbell rows...) to stay safe.
