Jewel cichlids are aggressive as well. It should be fine with the other aggressive cichlids you have though IMO (though I've never kept them, so I can't say for sure). The Albino, could it be an Albino Socolofi? And the blue one sounds like a regular Pseudotropheus socolofi
The Mbuna and the Jewel (Kenyi, Bumblebee, Albino Socolofi, reg. Socolofi, and Jewel) should be ok to stay in the 55g. The Duboisi do best in groups and the Front will outgrow the tank, so you should start to think about what to do with them. I'm not certain if the Duboisi could stay with the others, its possible it could. They do need an almost all vegetable diet, as they are more prone to bloat than other Africans, so keep on eye on your guy to make sure he stays healthy.
Its possible you could just get rid of the Frontosa when it gets about 5-6 inches and keep the others in your current tank, if you dont plan to upgrade. The pleco will also need to go eventually.
I personally wouldn't add anything else to the tank, even after learning what all types of fish you have. You have some really aggressive ones in there, so I don't think I'd add anything else to the mix. Other people may have more advice or could make suggestions because I planned my Malawi tank to have less aggressive types in it, so I'm not familiar with stocking a tank with really aggressive fish in it.
