So yes the human body has metals. In fact that is why Lead (Pb) is so dangerous. The body mistakes it for other vital metals and uses it instead.

When I studied chemistry, the term "metal" was normally used for the base element, such as Na or Fe. Ionized forms, such as Na+ or Fe(II) or (III), were considered to be distinct species. And the elements you list are normally found in the human body as positive ions, or in molecules or complexes such as heme; hardly ever as the base element.
