Where do the numbers go?

At the bottom of every page, centred.

The page number and the page count, so page 3 of 12 reads 3 / 12.

Can I number only some pages?

Yes. Use the page numbers for a range tool and write the range you want, like 2-4.

Put a number on every page, counting from 1 to the last page.
