It's generally not a good idea to house African cichlids with community fishes. African behaviour/aggression/territorial needs are completely different than those of most other fish; they "speak" two different languages. With that being said, the two in the community tank may be better off there until they're a bit bigger, before going into the cichlid tank. How many cichlids are in the tank? "Yellow with black fins" sounds like Labidochromis caeruleus, which are peaceful for African cichlids. I'm not sure if "electric blue Africans" refers to Sciaenochromis fryeri (Electric Blue Hap), or is just a description of the color. The yellow labs would be fine with the blue haps-- but there are a lot of electric blue Africans that would probably terrorize your yellow labs.
A word on tiger barbs: the behaviour that most people take for meanness is just barb behaviour. They chase other fish, they'll nip fins, etc. That's what barbs do. The trick with keeping barbs is to maintain them in groups of at LEAST five. This way, they occupy one another and don't bother the other fish in the aquarium
