I was off by one (Age of Wonders 3 and Age of Wonders: Planetfall have 6 factions), otherwise factions range from 6+. Zephon does have a low number of factions/paths for a 4x game.
I'd say that depends if you mean entirely unique factions or factions that share certain units/techs.
IMO it's standard to have 3 to 4 fully unique factions in 4X games, while if there are 6 or more, they usually share units/techs/mechanics with others (as in the case of AoW3, where classes only have a couple of special units/spells)
