Based on what I know, many fishes of the same species cannot be added into the same tank. But if it can co-exist as is a school fish, then these can be added together.

It’s really hard to determine, you only can try and put them together and see if they get aggressive, best to add them together rather than add one after another

Most of the time adding same type of fish into the tank that with a existing already territorial is quite hard regardless big or small fish.

What u can do is put the fish into the isolation box and see whether any aggression happen but this don't 100% guarantee as some fish only get aggressive after the new fish went in. The rate of catching aggressive is about 70 to 80% based on my experience.

If happen that u see aggression after release, u can use a mirror or feed a bit more to allow the new fish to acclimate to the new environment.

After all if aggression is not reside after few days, u should remove the fish else it will be gone soon or later only.
