Is the crew of one the capsuleer alone? If yes, then that'd be exactly the same as the old blueprints, where all the other mentioned frigates have a crew of one, and the Punisher has a crew of three. (Admitted, the given ratios would suggest that capsuleer Rifters, for example, would usually carry two crewmen on top of the capsuleer.) Actually there's a concrete number on one ship we know: The Reaper, if I remember correctly, has a crew of one.
Because the information, while certainly Prime Fiction, is still very, very coarse, as well. Minmatar, in specific, mentions "advanced designs". I'd assume that specific designs use a lot more of crew (EW, scanning etc.) compared to, say, Slashers which essentially are a few guns and a missile launcher slapped on an engine.
