what i call my father elder brother's wife
Your brother's wife is your sister-in-law.
That would be an uncle.
She would be your AUNT.
The word for uncle in Hindi is "चाचा" (chacha) for father's brother and "मामा" (mama) for mother's brother.
Simply, "Sister-in-law" English does not express seniority in relationships, such as an elder uncle, or a younger cousin, except when expressed with a separate adjective, like "elder". Otherwise, "elder brother's wife" is the most simple way to directly express that concept.
