All cluster B personalities have traits of one another. The list of symptoms and experiences do indeed point to that.
My first guess is BPD. 2nd NPD. cx3 thinks it's HPD. The one we never covered is APD.
While they do vary, handling them all is similar, and they can only really be managed if your foot is in the door.
EDIT: That being said, in order to manage that, appeal to the narcissist in them.
Overlapping traits don't establish that someone belongs to Cluster B. That's exactly why the same behaviors can point toward multiple possibilities, or toward none of them. You have BPD as your first guess, NPD as your second, CX3 has HPD, and now ASPD is the remaining category. That doesn't narrow it down very much.
More importantly, "handling them all is similar" doesn't follow from them sharing some traits. The appropriate response depends on the actual person and behavior, not simply putting them into a Cluster B category.
And "appeal to the narcissist in them" seems especially questionable. If someone already has problems with ego, validation, jealousy, and hierarchy, deliberately appealing to those traits could reinforce the exact dynamics causing the problems. It might produce short-term compliance, but that's different from actually improving the behavior.
I think that's also where your "management" framework becomes circular. You assume a Cluster B/narcissistic structure, interpret their reactions through that structure, and then recommend managing the structure rather than questioning whether the interaction is reinforcing it.
