Answer 1

jQuery.validator.addMethod("dropdowns", function(value, element) {

          var drop_val1 = $('#drop_1').val();
          var drop_val2 = $('#drop_2').val();
          var drop_val3 = $('#drop_3').val();


          if((parseInt(drop_val1)==parseInt(drop_val2)) || (parseInt(drop_val1)==parseInt(drop_val3)) || (parseInt(drop_val2)==parseInt(drop_val3)))
          { 
               return false;
          }
          else
         {
              return true;
         }


  }, "can not have the same value in 2 dropdowns"); 

then add it to your validation

            dropdown: {
                required : true,
                dropdowns: true
            }

this should work

EDIT

this works for multiple dropdowns

            dropdown1: {
                required : true,
                dropdowns: true
            },



            dropdown2: {
                required : true,
                dropdowns: true
            },



            dropdown3: {
                required : true,
                dropdowns: true
            }

dropdown1 , dropdown2 ,dropdown3 are your dropdown names
