Is this combination of fish alrite?

I have a 150gallon tank and we got the tank off of craigslist and the person gave me the fish with the tank and i just couldn't say no. He gave me

One Tinfoil Barb
Two Firemouth Cichlids
Four Pink Convict Cichlids
and Six Gouramis

I understand that cichlids are agressive already but he said that they aren't much of a problem.

I have no experience with these fish whatsoever, but typing them into aqadvisor says that these will be your problems:

Warning: At least 5 x Tinfoil Barb are recommended in a group.
Warning: When Firemouth starts to breed, they may become too aggressive to co-exist with Honey Gourami.
Warning: Convict is too aggressive to co-exist with Honey Gourami.
Warning: Your selected species may eventually require 106% of your aquarium space. You may need to deal with territorial aggressions later on. Try removing some of (Thorichthys meeki, Cryptoheros nigrofasciatus) or get a larger tank.

Convicts breed like bunnies. You will have fry if theres is atleast one male end female.
