Four bikes for free? I like that price, good find! I'd be inclined to convert the roller lever brakes over to period Sturmey Archer Drum brake hubs on the ladies loop frame though - The original Styrup brakes are useless if you need to drop anchor in a hurry...
It's a surprise to me that Raleigh shipped bikes out to the USA to be honest, especially the roadsters which are more designed for British torrential rain.
I only own two Raleigh bikes - depending on how you look at it; They manufactured under a slew of different brand names. The first is a scruffy '78 Chopper that I should probably get rid of, the other a near immaculate top of the range '62 Superbe with a 4spd dynohub, stainless steel westrick rims, steering lock, full chaincase & Dyno-luxe battery tube. I keep it dismantled & in storage as it's way to tall for me; I'd originally planned to use it as a parts donor for a smaller frame but decided that it was to good to break.

Your pair of Rudges are lovely. I had a 28" wheeled one of the same type which I sold on. Rudge chaincases are a pig when you get a rear puncture though!
