HTML markup is also coding?

Yes, but if we talk about terminology, PSD to HTML will be the most appropriate term to understand the English-speaking world.

A stretch, but you can also call this specialization of the HTML coder, but, in fact, there is no clear separation, as in the CIS countries, and develop Front End HTML coder

Is it possible in English to call the result of the work of writing pages of coding pages for the internet-store?

No.
The HTML markup is HTML markup and CSS styles.
markup and styles page-developer - developer of markup and styles (layout template without js-code)

This is commonly called "slicing PSD to HTML". Or just "PSD to HTML".
