I looked through ghost of a doll, as well as reverse-image searched for you, and didn't come up with anything.
My bet? They're not an 80s toy. I'm going to guess that they are plushies that someone has modified to be more fairy kei... or they are from one of the lolita/pastel/fairy kei stores in japan... The reason I think that is because of the lace around the bellies.. they just seem to be more deco things than play things.
The giraffe though looks to be a babie's toy of some kind :--) The moon has that bumpy minky fabric that you see in baby toys a lot.
Of course, I could be completely wrong.. but it's my guess that its one of those fairy kei plushes that there aren't really any duplicates of.
