I think the 8N is a BSN, maybe the automated molding period?

No idea about the 9 but it looks like this Erie, https://everythingold.ca/products/no-9-unmarked-erie-pre-griswold-cast-iron-skillet-with-heat-ring

Also found a 11-1/4 small logo Griswold and a GSW.

I'm keeping the GSW for sure but of these other 3 which should i keep and which can go back to being a camp skillet?
