Elf,
Troll,
Gnom,
Zwerg,
technically we don't have a Kabauter in Germany, but there is that one book and tv series "David der Kabauter" which I now suspect to be a Dutch book that has been translated - as a kid I thought it was something like a "Klabautermann", but that's a whole different creature that lives on boats and warns the captain when there's danger and otherwise makes noise - the Kabauter is probably somewhere between a Zwerg and a Gnom and seems like it was the origin for a very German concept of the Gartenzwerg = garden gnome, especially visually and from what I remember of the books I had they also live in nature or gardens,
Drache, sometimes Drachen, depending on regional dialect,
Zentaur,
Meerjungfrau, sometimes Seejungfrau,
Sirene,
Nymphe.
Most words are the same or very similar which is why I could usually understand Dutch texts (like when we would go to Arnhem or Harderwijk) even as a kid but the pronunciation is different enough that one has to get used to it first. 😅
