Nice looking fish! GL with them! Have you tested water with api liquid test kit?

Nice looking fish! Oscars are great pets. Just a heads up, these last pics showing your Oscar's forehead seem to show the beginnings of HLLE (head and lateral line erosion/ "Hole in the head") disease. This is thought to be brought on by high nitrate levels in the water. The 80 gallon tank you have, as some others have said, is not enough volume of water to keep that many big messy fish without high nitrate levels. I would only consider it enough for a single full-grown Oscar. I would definitely recommend you get either a much larger tank for these guys, or find new homes for most of them, if you want them to stay healthy in the future.
HLLE caused by hexamita happens when the hexamita move to the fish's sensory pores and cause the tissue surrounding them to erode. Internal hexamita infections can be treated with Epsom salt soaked food or injected into the fish's mouth with a pipette. I have not used Esha hexamita, it may be a good solution for internal hexamita but I have no experience with it.
The hole in the head though, seems to be irreversible once it is well established. So I doubt the medicine would do anything about the lesions. Clean low-nitrate water boosts the fish's natural immune system to fight the parasites and stop the spread of the holes.
I only see very early signs on your fish, it may be easy at this point to stop it from getting any worse. Do you test your nitrates? Your tank has a very high bioload for the volume of water, I am guessing the nitrates might be high. Over 20ppm is "high" in my opinion, people have different opinions on this. Some say up to 40ppm, some try to keep them at 5 or below. 20ppm max is a good compromise IMO. If your nitrate levels are higher than 20ppm I would look into re-homing many of your fish or start doing large water changes more frequently. Like me and a few others have said, the stock level in your tank isn't feasible for healthy fish long-term.
If you have more questions feel free to ask! Highlighted your pic below to show what I think is the start of HLLE.
I have a single fish in a 125gal tank.
I do fin lvl water changes every third day to keep my nitrates below 10. That's one fish. Your nitrates have to be in the 100s or better with that many fish in such a small tank unless your doing fin lvl changes daily. Then you live feed on top of it..... that adds lots of bioload of bits of them fish the O's spit out decomposing.
Also in these new pics looks like the parrots are pairing up. This will cause a lot of chaos of fighting, turf wars and in the long run make your fish more susceptible to diseases due to all the stressors.
