Your mother's brother-in-law is your uncle.
They call their Mom Mommy or Mom.
Your parent's brothers are your uncles and your parent's sisters are your aunts.
Your mother's sister is your aunt and her husband is your uncle. If he has no brothers, his sister-in-law must be either your mother or another one of your mother's sisters (your aunt)
If she is now married to your shared father, she is your step-mother. Otherwise she does not have a direct relationship to you.
