Just get a decent tube tester - money well spent. the time trying to do it with a multimeter is not worth it, not to mention you cannot do transconductance readings. About the best you could do would be filament tests.
There is a plethora of RCA or Telefunken handbooks on Ebay , where you'll find all the pin diagrams and for the rest I suggest, you follow Ed's advice. Get a good old Hickock or Western Electric tube tester, there are lots of them on Ebay as well. The better ones are expensive though, because much sought after. Cheers,
