But how do I get the value of this page number so I can add if else conditions according to it and change the header content?

You'll want to use bfo's header and footer macros. You can then specify which header macro to use based on the page number. This can be done explicitly on the body element and pgbr tags, or via the CSS (have a google for that).
You infamously can't set a different header/footer for the "last" page. A well known limitation of the freemarker > BFO rendering pipeline

#page1 {
header:nlheader;
header-height:14%;
}
#page2, #page3, #page4, #page5, #page6 {
header:nlheader2;
header-height:12%;
}

#page2, #page3, ... #page∞<body header="nlheader2">#page1 {header:nlheader}4 Views
