Try this steps to add different footer in word document
As a default in Word, every resulting header and footers connect to the past page's header and footer.

This activity will make a segment break empowering you to apply various ascribes, (for example, headers and footers, edge settings, page sizes, directions, and so forth) to one segment of the report without On the following page after the break, explore to the header or footer zone and double tap that region to make it editable (alluded to as Design mode); this activity likewise shows the header and footer toolbars. Next, select the current header or footer and snap the Link to Previous alternative (as hovered underneath) to break the header or footer association.
When the connection is broken, you can alter or change the new area's header or footer without influencing your past headers or footers. Keep on embeddings Next Page breaks and afterward break the connection associations for each resulting section where you need various headers or footers to show up.

I hope this helps!
