you can do it using async:

<script type="text/javascript" src="https://raw.githubusercontent.com/caolan/async/master/dist/async.js"></script>
<script type="text/javascript">


    var requestUrls = [];//array of urls
        //request all data
async.each(requestUrls, function(url, callback) {
    $.ajax({
        url:url
    }).done(function(data){
        console.log('data',data);
        callback();
    }).fail(function(err){
        console.log('err',err);
        callback(err);
    });
}, function(err) {
    // if any of the file processing produced an error, err would equal that error
    if( err ) {
      // One of the iterations produced an error.
      // All processing will now stop.
      console.log('A url failed to process',err);
    } else {
      console.log('All url have been processed successfully');
    }
});

</script>

Read promises and defered.

var ajax1 = $.ajax({ 
  dataType: "json",
  url: "url",
  async: true,
  success: function(result) {}                     
});


var ajax2 = $.ajax({ 
  dataType: "json",
  url: "url",
  async: true,
  success: function(result) {}  
});

$.when( ajax1 , ajax2  ).done(function( a1, a2 ) {
   // a1 and a2 are arguments resolved for the page1 and page2 ajax requests, respectively.
   // Each argument is an array with the following structure: [ data, statusText, jqXHR ]
   var data = a1[ 0 ] + a2[ 0 ]; // a1[ 0 ] = "Whip", a2[ 0 ] = " It"
   if ( /Whip It/.test( data ) ) {
      alert( "We got what we came for!" );
   }
});
