The terms "elementary" and "primary" often refer to levels of education, but they can have different connotations depending on the context. "Elementary" typically refers to the early stages of formal education, usually encompassing grades K-5 or ages 5-11, focusing on foundational skills like reading and math. "Primary," on the other hand, can refer more broadly to the first stage of education and may include both elementary and early childhood education, depending on the educational system. In some regions, "primary" is used synonymously with "elementary," while in others, it may denote a broader or slightly different educational framework.
The two are synonymous. There is no difference.

Any group of keys or columns (may be one or more than one) which can be used to uniquely refer to any row is together called as candidate key.A primary key only one column name which can be used to uniquely refer any row.there is no much difference b/w these two except the number of columns in consideration.
I am supposing that key means primary key.Superkey is any subset of attributes that uniquely identifies the tuples of a relation. This subset need not be minimal, that is, one can remove some attributes from it and it is still uniquely identifying. If all redundant attributes are removed you get a subset what is called primary key.
