Yes you can! In my experience in keeps lots of zebrasome together, they seem to do better with odd numbers. You have 3+ which is great approach. But for some reason the odd numbers lead to less issues with personality conflicts.
You can add a sailfin later. Sailfins grow at a much faster rate than purples. So be aware of that. Purples are definitely more aggressive that Sailfins, so getting a sailfin the same size at the purples should lead to good results.
And once you have established this group of purples, you can add a gem tang, or a black tang - if of equal size - without too much of a chance of major problems (after the first 24 hours).
For some reason, if you get the opportunity to add yellows (Hopefully Hawaii opens again), then you have to add them in groups of odd numbers as well.
And the Zebrasomas are usually more jerkish to other Zebrasomas - so adding a Achilles, Powder Blue, Naso, etc won't create too much turmoil if it's a reasonable size for the Zebrasomas.
