Stuff I had in mind:

Tahu has buff legs:
Walking through lava
Surfing

Kopaka's skinny with a buff-ish torso:
Withstanding cold
Navigating through snow

Pohatu's small with big feet:
Kicking stuff around
Better grip
Faster running

Lewa's tall, has rubber bands:
Swinging on vines
Tool storage
Camouflage

Gali is tall, slim:
Better for swimming
Climbing

Onua is small, slim:
Navigate through tunnels
Faster advancing while digging (smaller tunnels)
Quick getaway in case of cave-ins
