Image 1 I'm pretty sure is meant to be a Shrake. I'm not sure what you mean in Image 2 - the beast in the corner is probably a troll of some kind, the face in the smoke might be a Genie or ghost, the fairies are obviously fairies, the birds... no idea. Img3 is some kind of dragon, Img4, now FB has come out, I think is an Occamy, given placement and depiction, and I think the last is of another kind of dragon.
