Fire eel- terrible choice IMO for what you've got. Also, grows too large.
Bichirs- should be fine, depending on the species
Gar- gets waaaayyyyyyy too big for this tank
Clown knife- gets waaaaaayyyyyyyyy too big for this tank
Tinfoil barb- prefers groups, gets really big (14", but bulky)
Leaf fish- what species? Probably gets very little food with those tankmates
Bala shark- prefers groups, gets big and fast, too big and fast for this tank
Monos- brackish to full saltwater when adult
Silver dollars- prefer groups
Pleco- species?
Red chalceus- grows to 10", is rather nervous and fast. Potentially borderline ok
Angel- would be fine, but tankmates are unsuitable.
mof - I used your scheme, hope you don't mind
