Here are some typical flap landing settings, which do vary depending on airline standard procedure.
B737, Flap 30 (Flap 40 is only recommended for short fields and the -300/400/500 do not meet Chapter III regulations with this setting)
B767, Flap 30
B747, Flap 25 (some use 30).
Airbus FBW models, Flap Full (the actual degree of flaps depends on the aircraft, ie. 340-32°, 320-35°). Flap 3 may be used in some situations (340-26°, 320-22° - not 100% certain about the 320)
High flap settings such as Flap 50 are really only found on older design aircraft such as the 707 and DC-10/MD-11.
