The wife of your brother is your "sister-in-law" In English, this is true whether the brother is older or younger than you are.

Sister In law
While generally referred to as a Sister-in-law, there is no relationship.
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.

In the English language there is no difference between the wife of an elder brother and the wife of a younger brother or of a twin brother. The wife of any brother is your sister-in-law. If you are actually talking to her, however you should just call her by her name. Nicknames are fine too.
Your wife's nephew is your nephew, but the English language has no relationship term for your nephew's wife. Just call her "my nephew's wife."
Your brother's wife is your sister-in-law. The English language has no relationship term for the brother of your sister-in-law. He is not considered to be related toyou, although he is your brother's brother-in-law.
