How I hate my computer, I just spent seriously an hour typing a response, and somehow, I or it pressed a back button, and bye bye it all went! Argh!
Anyways, I first went and listed your fish by what I believed were minimum tank sizes for each:
blood parrot-
55 Gallon
electric blue crayfish-
20 Gallon
rams (2)- 20 Gallon
celestrial pearl danios (6)-
10 Gallon
endlers (3 males)-
10 Gallon
swordtails (8 fry)-
30 Gallon
bristlenose plecos (2)-
20 Gallon for a single breeding pair or 2 females, 55 for 2 males, Can you sex them yet?
cherry barbs (10)-
20 Gallon, but for 10, I'd say 29 Gallon
congo tetras (6)-
30 Gallon, 55 would be better though
syno petricola (1 will be 3)-
30 Gallon
cutteri cichlid-
20 Gallon for one, 29 Gallon for one with other fish
bluntnose minnows-
20 Gallon (these are just basically rosy reds, right?)
fish id like to have
firemouth-
55 Gallon
severum-
75 Gallon
corys-
For dwarf cories 10 gallons, for Panda Cories- 20 Gallons, for any other other cory- 29 gallons
honey gourami-
10 Gallon
loaches-
For hillstream and panda loaches (and similar) 10 gallons (with tons of live plants, high O2, TONS of algae), for kuhli loaches, dwarf chain loaches, and horse face loach 20 gallons, for any loach between 4-5" 55 Gallons
I know you said you didn't want to use the 10's but if you set them up nice with lots of plants and make them dedicated to each species in there with dwarf fish, you'd have some nice set ups. Here's my stocking idea.
~10 Gallon #1 *with sand for substrate*- 6-8 dwarf corydoras, 1 honey gourami, 3 male endlers
~10 Gallon #2 *cool water 20-24C, with lots of plants, round rocks covered in algae, and high O2 levels via spray bar, etc.- NOT BUBBLER*- 3 hillstream or similar loaches, 8 Celestial Pearl Danios (I'd get 2 more)
~10 Gallon #3 *I noticed killifish were added on to the list

* -Killifish, someone more experienced will have to give you numbers
~20 Gallon- EB Crayfish and the 6 Bluntnose minnows
~29 Gallon- 2 Rams, 10 Cherry Barbs, 1 Bristlenose
~30 Gallon- 2 Angelfish (hope you don't have a breeding pair), 6 Congo tetras (are Congo tetras fin nippers?), 1 Bristlenose pleco
~55 Gallon- Blood Parrot, Cutteri, Fire mouth, (you MUST have MANY territories for all of them, lots of open swimming space but LOTS of caves)
Only thing is the swordtails and syno petricola. I wasn't sure where to put the swordtails, and the synos need 7.6-9 pH, they are really better off in a rift lake tank, all mine died because my pH was too low

Lesson learned. (and my rainbow shark helped pick off the rest of course). You could probably put the swords and synos in a tank of their own (have a pH of ~7.7), but it'd need to be at least 30 Gallons
