GLH: Ok, after way too much time, I finally found the names for the rest of the untagged characters in this image here. The young redhead with red-eyes is "Maria". I already tagged the green-haired young elf/dragon girl "Tiki". That just leaves the blue-haired "Athena", and the brownish-red-head "Linde".

It also seems that there are next to no tagged images of these characters on this site.
