So a phrase like "his excellency" isn't just a noun with a possessive attached; it's a lexical unit in its own right. And it's a lexical unit that's only ever used pronominally. You can't, for example, say "there were seven his excellencies in the room" (or even "there were seven excellencies in the room", unless by jocular wordplay).
I think *
seven his excellencies is out for separate reasons, namely (a)
his can't refer to multiple individuals, and (b) possessive pronouns can't be immediately preceded by numerals.
seven of their excellencies seems fine to me, and so does
their seven excellencies at a stretch.
Someone could try to make an argument that if
your excellency was really a second-person pronoun it would trigger second-person agreement, which it doesn't. (
Your excellency is ... not
Your excellency are ....) I think such an argument would be moderately convincing, but then we do also have second-person pronouns like German
Sie or Spanish
usted that similarly occur with third-person verb endings.
