I need a answer

My friend said that she is a goddess of wind is that possibly

No, it isn't possible.

The Gods and Goddesses are not physical beings they are more like spirits. Your friend is a human being, not a Goddess. She is either pulling your leg, role-playing, or possibly even delusional...but she is NOT a Goddess.

Simply no. You cannot be anything other than a human. Things like what your friend stated is all pure fantasy.
