My rating is: Extremely overstocked.
Dont get me wrong, I like large cichlids... But they need to be housed properly.
Firemouths grow to about 6 inches. Dempseys grow to about 10 inches. Terrors grow to about 8 inches. Gold nugget, eh, dont know, your tank is still overstocked. If its a jaguar cichlid, thats another 16 inches of fish...
Seriously, the Dempseys will probably kill everything unless the Jaguar or Terror can catch up to it in growing speed. Then, the Jaguar wins hands down. Its one of the meanest cichlids.
A single Dempsey needs around 55 gallons. Yes, a SINGLE Dempsey. Yet you have 4 in something not even close to what they need. Not to mention everything else... The Jaguar will eventually need a 125-150 gallon tank. God. I could go on and on here. But Im going to hope someone else will take over for me.
But in the end, all these fish will die. You shouldnt have done this. This is probably the worst fish stocking Ive seen on here in a long time.
