The Stars pictured above going by the ribbons, are 1939-1945 Star, Atlantic Star with ACE clasp, Italy Star and Africa Star.
Naming on Stars/WWII medals points to South African, Australian or Indian units (may be one or two other Commonwealth countries too) unless privately named by the recipient.
The value of any Empire/Commonwealth medal is in the research, if killed, then where? If wounded where? Unit/rank/name etc.
You could be sitting on a lot of money especially if the highly faked Air Crew Europe Stars are genuine. See here for comparisons http://www.northeastmedals.co.uk/britishguide/aircreweurpestarcopyfake.htm
