First, there's the big four. Earth, Air, Fire, and Water. I'm sure you know what they can do.
Then there's the smaller elements who don't have the same kind of strengh as the big four:
Lightning- Can control electricity to attack enemies
Time- Can go back in time, but are wise enough to know that you can not change the past.
Space- Can travel anywhere at the speed of light. They can mess with dimensions, but only at a great cost.
Ice- Obviously controls ice.
Light- Peaceful and friendly, but they can bend light to their will.
Herbs- They do not fight, but heal. They get along with Earths very well.
Toxic- Poisanous and venomous.
Entropy- Can control minds, unless the person they are trying to control has trained in the art of blocking minds.
So now that you know what they are, lets begin!
