A very useful list indeed. Quite a few as Frederic already noticed...
My own interpretation of the important ones, I guess based both on what I have read and the similarity between some German and Swedish words, are
Fliegerhorst - a major military airfield - not supposed to be used by civil aircraft
Flughafen - a major civil airfield - not supposed to be used by military aircraft
Flugplatz - major field - used in more general terms and could be either of the above and perhaps a combination of both.
The addition of See of course identifies a place where basically only water landing capable aircraft were handled.
