So let's go:

ELmax = Ernst Leitz + Max from Max Berek
ELmar (new computation of the Elmax)
Hektor : dog of Berek
Rex (Summarex?!) : idem

Noctilux : f/1 or f1,2
Summilux : f/1,4
Xenon : f/1,5
Summarit and Summarex : f/1,5 or f/2,4 (on Minilux )
Summar* : f/2 (*f/3,2 on Leica Mini 3)
Summitar, Summicron : f/2
Thambar : f/2,2
Elmarit, Tele-Elmarit : f/2,8
Elmar : f/2,8, f/3,5, f/4, f/4,5
Summaron : f/2,8, f/3,5, f/5,6
Hektor :f/2,5, f/4,5
Telyt : Long Focal ot Tele

Super-Angulon = Schneider name
Hologon = Zeiss name

Marc correct me if I'm wrong,
