Answer 1

Something like these?

platform.registerBackButtonAction(()=>{
      // get the current activeNav
      let nav = app.getActiveNavs()[0];
      let active = nav.getActive();

      //crete as many difrent conditions as you need ...
      if(active.instance instanceof Pagename){
      //work u wanna do with dat page name
      }
      if(active.instance instanceof Pagename2){
      //work u wanna do with dat page name
      }

      //Go back
      nav.pop(); 

    },2)  //<- this is priority

You can also check if you can go back with:

if (nav.canGoBack()){
    nav.pop();
}
