So in terms of powers, do you go with one element and then list their powers based on that element? 

Or do you mix and match? I.E. If I wanted a Guardian who was an Earth manipulator would that be okay?

Hi. If there is a focus on one element, the magic of that element can/will be more powerful. But, you can mix the elements for more versatility. And sure, if you want to focus on Earth, then that's totally fine.
