In English, your husband's brother is your brother-in-law, and his sister is your sister-in-law. Therefore, your husband's brother's wife is your sister-in-law. However, in some cultures, this relationship has a different name. For example, in Indian English, the husband of one's sibling-in-law is referred to as a co-brother.

Husband's brother-in-law
A husband's brother-in-law is the brother of one's husband. The term "brother-in-law" is used to signify that the relationship is through marriage and not blood. In Indian English, the husband of one's sibling-in-law is referred to as a co-brother.
The term "brother-in-law" can also be used to refer to a spouse's sibling. However, this usage is not technically correct, as the spouse's sibling is not directly related to the person in question. In this case, the spouse's sibling is the husband's brother-in-law, and their relationship is one of affinity, or kinship by marriage.
The husband's brother-in-law's wife is the husband's sister-in-law. This is because she is now part of the family, and the "in-law" suffix signifies that the relationship is through marriage.
The children of one's siblings-in-law are called nieces and nephews, with the specification of "by marriage" to differentiate from blood relationships.

Brother-in-law's wife
Your husband's brother-in-law's wife is your sister-in-law. This is because your husband's brother-in-law is your brother, and his wife is your sister-in-law. This is a reciprocal relationship, as your husband's brother-in-law's wife is also your spouse's sibling's spouse. In Indian English, this relationship can be referred to as a co-sister.
In-laws are people you are related to by marriage. Your siblings' spouses are your brother-in-law or sister-in-law. Therefore, your brother-in-law's wife is your sister-in-law.
Some people may refer to their brother-in-law's wife simply as their brother-in-law's wife, or by her name. However, technically, she is your sister-in-law, as she is now part of the family, and the "in-law" signifies that this relationship is through marriage.
It is worth noting that the term "brother-in-law" can be used for both a spouse's sibling and a spouse's sibling-in-law, which can be confusing. This is why some people may prefer to use the terms co-brother or co-sister, or simply refer to the person by name.

Co-sibling
In the English language, there is no widely recognised term for the relationship between yourself and your husband's brother-in-law. The closest term would be "in-law", but this is a general term that can apply to many different relationships.
In Indian English, the husband of your husband's sister (your husband's brother-in-law) would be referred to as a "co-sibling", or more specifically, a "co-brother". This term recognises the reciprocal relationship between a person's spouse and their sibling's spouse.
In other languages, there are often more specific terms for extended family relationships. For example, in Russian, your husband's sister would be called "сноха" or "невестка", and her husband would be "зять".
Some people may choose to simply refer to their husband's brother-in-law by name, rather than using a specific term to describe the relationship. Ultimately, the choice of how to refer to this person is a matter of personal preference, and different families may use different terms depending on their own customs and traditions.

In-laws
The term 'in-law' is often used to refer to a person's spouse's family members, even if there is no direct blood relation. For example, your husband's brother is your brother-in-law, and his sister is your sister-in-law. Their relationship to you is through your marriage to your husband, hence the term 'in-law'.
The reciprocal relationship between a person's spouse and their sibling's spouse is also referred to as a sibling-in-law. In Indian English, this can be called a co-sibling, specifically a co-sister for a female sibling-in-law, and a co-brother for a male sibling-in-law.
The children of one's siblings-in-law are called nieces and nephews, and if necessary, it can be specified whether they are related 'by marriage', 'by blood', or 'by adoption'.
While there are no specific terms to refer to more distant relations, such as your husband's brother-in-law, they can still be referred to as 'in-laws' due to the marriage connection.

Affinity
The relationship between a person and their husband's brother-in-law is one of affinity, a type of kinship that arises from marriage. In this case, the husband's brother-in-law is the spouse of the husband's sibling. While the term “brother-in-law” is commonly used to refer to both a spouse's sibling and their spouse's sibling-in-law, technically, the husband's brother-in-law is not a blood relative and is simply the husband of one's sister-in-law.
In some cultures, there are specific terms to distinguish these relationships. For example, in Indian English, the husband of one's sibling-in-law is referred to as a "co-brother". Similarly, in Russian, there are distinct terms for various relationships, such as "сноха" (snokha) or "невестка" (nevestka) for the wife of one's brother.
The English language, however, lacks a specific term for the relationship between a person and their husband's brother-in-law, and they are often referred to as simply “in-laws”. This can lead to confusion, especially when trying to explain the relationship to others.
Despite the lack of a specific term, the relationship between a person and their husband's brother-in-law can still be significant. They become part of each other's extended families through marriage, and the closeness and satisfaction of this relationship can impact the dynamic of the triad it forms with the sibling and spousal relationships.
