If the First Cousin of your parent has a child, that child is your Second Cousin. You have one or more Greatgrandparents in common. That is the deifnition of a Second Cousin.
Your child and your great nephew's parents would be first cousins. Their children would then be second cousins. And if they have children, they will be third cousins.
No. It shouldn't pose a problem.
Your parent's first cousins are your "first cousins once removed". When referring to cousins, the number indicates (first, second etc) indicates the number of generations since you had a common ancestor. For first cousins the common ancestor was two generations previous (i.e grandparents), for second cousins it was three generations and so on This only works if the cousins are in the same generation. Therefore the 'removed' indicates the number of generations separating the people concerned. When you were born, you were one generation removed from your parents first cousins i.e you were their 'first cousin once removed'. The child of your parents cousins are your second cousins. It may be easier to understand this with diagrams rather than with words.
Your child and your niece are first cousins to each other. Your child and your niece's child are first cousins, once removed.
Your child and your first cousin's child are second cousins. A full generation is another set of cousins. For example, the second cousins' children will be third cousins, etc. Now here is the tricky part. You are a first cousin once removed to your cousin's child and your cousin is a first cousin once removed from your child.
A child of two first cousins is the child of the parents and they are the child's mother and father. As the child of one first cousin, the child is also the first cousin, once removed, of the other parent. That, however, is of no importance. The closer relationship of parent and child is the one that really matters.
Your child and your great nephew's parents would be first cousins. Their children would then be second cousins. And if they have children, they will be third cousins.
Let's assume you are talking about first cousins.If they are children of the same cousin they are siblings (brothers and sisters).If they are children of different cousins and the cousins are both children of the siblings of one of your parents, then the cousin's children are second cousins to each other.If one of the cousins is a child of a sibling of one of your parents and the other cousins is a child of a sibling of your other parent, then the cousin's children are not related to each other.If you are talking and the children of second cousins, they children are siblings, third cousins or not related.If you are talking about cousins who are once, twice or more removed from you, the possible relationships become too complex to discuss here.
No. It shouldn't pose a problem.
They would be second cousins. Your child and your grandniece's parent are first cousins. There are no 'removed' involved because the generation difference between the common ancestors (your parents) is the same.

Your cousins child is your first cousin once removed.
Because that is the way it works. Your cousin's child is your cousin once removed because you are separated by one generation while you and your cousin are of the same generation. Your cousin's child is not your neice or nephew because that relationship is reserved for the children of your brothers and sisters.
Your child and your first cousin's child are second cousins. Your child and your second cousin's child are third cousins to each other.
