+1 to Bob.
4 months is a bit young for them to be breeding but it looks to me like the fish in the bottom left pic is the male and the top, female. Males have the brighter and better coloration. When (or if) they do pair off, you'll notice that the male will chase away all but one of the fish from his home. The unchased fish is his female of choice. If you see this, you'd be wise to either remove the pair or move the leftovers to another tank as there is a very real probablility that the pair will kill off the intruders.

Hope this helps.

you might want to vent them tbh. from what i have seen, jewel males can colour up pretty quickly and i think those are females.... could be very wrong! have a vent (http://www.everything-aquatic.com/2009/02/sexingventing-cichlids.html), and good luck getting a pair x

All very helpful, thank you! Looks like venting is the only way to be sure but il give it a while first!
