Firemouths and Jack Dempseys

I dont want to risk stunting my FMs they are one of my favorite fish. I want to move them in my 40g and take the full grown JD pair and put them in the 20g. Will the pair being in the 20g affect their health.The tank is clean and i do 20% water changes every week.The male JD is 11 in and the female is 4

Yes they will die. 20 gallons is wayyyyyyy too small for even one. Are you serious, is this for real that you want to put an 11 inch fish in a 20 gallon tank? The tank is most certainly not clean with only a 20% water change weekly. You would need 100% changes twice a day just to not affect their health for a short time, while you find a proper size tank for the pair. 75 gallons or more.

If the firemouth is your favorite, rehome the others, or get a 20long/29g specifically for the firemouth.

could i swap the JDs for my convicts in a 45 gallon?The male is 7in and the female is 4.5.

That would work better but a 20 is small for cons unless it's only 1 or 2 and their small.

If its a 20 long it may be ok with the cons or the fire mouths
if its a tall that may be a problem. 30 x 12 would be better than 24 x 12.
