Sets per workout
 

Do you do the same amount of sets in a workout? For example, if I do 5 sets on my biceps for an exercise, should I do 5 sets for my triceps?

Not sure what your question is, but I do ALOT more tri work than bicep work.

For proper balance at the chest/back or hip flexors/extensors, this logic would work. However, since your triceps are significantly larger than your biceps, in order to keep balance in them you would need to work your triceps at a higher ratio with more volume and intensity.

Your triceps make up 2/3rd of your humerus. Your biceps is a small two headed muscle that is stimulated significantly without specific focus. Anytime the arms are brought into flexion against gravity, the biceps are stimulated; this means bent over rows, pullups, chinups, face pulls, all work the biceps adequately.

I would do a 2:1 ratio for your biceps and triceps. If you do 1 exercise for your biceps, try to get in 2 for your triceps.

No you do not need to do that same amount of sets per body group.

No you do not. You can do a few sets for the biceps, and then do extra sets for the triceps. It just depends on what you really want to focus on.
