In the United States, our kinship system does not have a separate word to refer to the spouse of a cousin, so on that basis you can argue that someone who marries your cousin is not "related" to you. However, in a sense you *are* related to that person, especially if you have regular or close contact with your cousin and his or her spouse, so you can choose to refer to the spouse as a cousin if you want to create a greater or inclusive sense of family.
In some cultures you would be related and in others you would not. In western culture, you would not be legally related to your sister-in-law's cousin.
It is okay to marry your cousin, its not incest, your brother? no
yes
Islam is one of those religions that believe it is acceptable to marry your cousin. It should be noted, however, that "cousin brother" and "cousin sister" have no meaning in the English language. Your brother or sister is a person who has the same parents you do. Your cousin is someone who is the child of your parents' brother or sister, or of your grandparent's brother or sister.

The English language does not use the phrase "cousin brother." The brother of your cousin is also your cousin.
A brother can't marry a sister it's against the law, but you can marry your 2nd cousin and down.
A step brother's cousin is no relation to you.
Your cousin's brother is also your cousin, but the cousin's wife is not related to you.
Yes you can marry her. She has no blood relation to you. She is just the niece of your brother's wife from her side. It is no different than if two cousins married two women who were sisters.
