function checkBox(){

   var alert1 = document.getElementById('alert1').checked;
   var alert2 = document.getElementById('alert2').checked;
   var alert3 = document.getElementById('alert3').checked;

   if(alert1 == 1 && alert2 == 2 && alert3 == 1){
      do somthing...
   }

   if(alert1 == 1 || alert2 == 2 || alert3 == 1){
      do somthing...

I had hard times to understand what you need. Hope this is what you are after

function (){
  if(alert1 == 1 && alert2 == 2 && alert3 == 1){
    //do some stuff
  } else if (alert1 == 1 || alert2 == 2 || alert3 == 1){
    //do other stuff
  }
}
