Two bits of uneducated information:

(1) I believe that the font name that is displayed by font managers is embeddeb in the font file and not necessarily what you call its file on disk.

(2) Fontographers call a font a single weight (point size) of a single style because that's how fonts came, cast in lead, one "font" per drawer.
