I have just purchased one of these devices on eBay. Will it be able to ring all four of the dumb unpowered analog telephones in my house?

Most likely, no problem if they aren't mechanical ringers. Each phone should have a REN (ringer equivalent number) and the SPA should document how many RENs it can drive. But 4 should be no problem.
