You need to wait until your tank is healthy again, probably a month without any issues. You may need your Q tank for sick fish in the near future if only a few haven't recovered (or died, sorry, you're not out of the woods yet 
). My mantra, water changes!
As for what order to add fish, hard to say. I'm going to assume QT is fully cycled for a tankful of fish. Cardinals will likely to be smaller than adult size but I would do 2 batches of 10 each if you need to, your lfs may not have 20 & you don't want to mix "batches" from different shipments or sources. If all is good with QT cycling & source you might do all at once. Be careful! Test often!
Then maybe a young male ram. Males alone are more mellow & females mature at a smaller size. Add the female last of all, she will change the dynamic of the tank.
After the male ram, maybe the honey gouramis. Remember, a true pair or 2 females & 1 male. Do you have live plants? I don't recall, but some floaters will help them feel happy...& help the SAE to be less apt to jump. Not duckweed!!
Last of all the female ram. Ask if you can get an even exchange for "her" if it turns out to be a male (same with the gouramis). But research the M & F differences, fish catchers don't always know more than you.
Go slow! You want a happy healthy tank, not just a stocked 1. In some ways it'll depend on what available when you're ready.
& we're going to need pics!
