No, very much no. The Centauri map onto an empire in decline, so you could point at the late Roman empire, the late Byzantine empire, the late British empire, &c., where they haven't caught up with the reality of their situation and still have delusions of grandeur of the times when they were still ascendant. The Minbari don't neatly align onto any human cultures. Sure, you can pick out elements of various Far Eastern and Near Eastern cultures, but there's no actual 'mysticism' there. If you wanted to compare them to anything, they're basically less hot-headed Klingons. The Narn are not 'Dark skined prominant skeletal featured war like people'. To paint them as such misses the point of their whole arc throughout the show, and in particular that of G'Kar. They're a deeply traumatised people trying to recover after a long colonial occupation. About the only reason why you're projecting that onto them is that many human beings from colonised parts of the world have dark skin, but the Narn are not actually portrayed as warlike: that's something the Centauri liked to portray themselves as to excuse their treatment of and subsequent high-handedness with the Narm. From my perspective as someone from Ireland, I see ourselves in the Narn, after centuries of similar treatment from our neighbours to the east. I would recommend you go back and rewatch the show past the first season.
