Your brother-in-law's children are your nephews and nieces.
There is no genealogical relationship. He is just your son-in-law's brother.
Your mother-in-law's brother and his children are not related to you.He is your childrens' uncle and his children are first cousins to your children.
If your brother adopted you, you are his son or daughter and his in-laws are your grandparents by adoption.
Your wife's sister's husband is your wife's brother-in-law, but is not related to you.
They are brother-in-laws.
Since it would be your sister who had the child with her husband (your brother-in-law) then that would make their child your niece or nephew.
There would be no relationship as you do not share a common ancestor. If your brother-in-law is married to your sister, then her daughter is your niece, her husband would be referred to as your niece's husband.
Not at all. There are many men and women who date and consequently marry the siblings of their brother-in-laws and sister-in-laws. Some folks may find it strange to "keep it in the family", but there are many success stories of this nature. Technically, your brother or sister's in-laws are not YOUR in-laws, and you have no real legal relationship to them. If my fiancee had a nice brother for me to set my younger sister up with, I'd go for it in a heart-beat.
