The officially recognized elemental mazzelhs are:
Fire, Water, Air, Light and Grass (every mazzelh will claim that grass is an element).
Furthermore there are shadow mazzelhs (darkness?), but they are considered more of corrupted mazzelh spirits than elementals.
Subelemental mazzelhs such as stone, wind and ice can be created by clerics/sorcerers/wizards.
@firetail:
Human as an element?? LOL!
