$q.all - access individual promise result?

I'm a bit new to $q angular promises. Here is my code structure:

$q.all(promises).then(function(results) {
    results.forEach(function(data, status, headers, config) {
        console.log(status);
    });
    $scope.saveDocumentCaseState();
}, function errorCallBack(response) {
    console.log('error while mass update case entries');
    console.log(response);
    $scope.submitToWsSuccessful = 2;
});

Is there a possibility to access the result of each promise when it has been executed before the next one?

So assuming that you receive an array with an arbitrary number of promises from an angular factory called promiseFactory:

var promises = promiseFactory.getPromises(); // Returns an array of promises

promises.forEach(function(p){
  p.then(promiseSuccess, promiseError);

  function promiseSuccess(){
    // Do something when promise succeeds
  }

  function promiseError(){
    // Do something when promise errors
  }
});

$q.all(promises).then(allSuccess, allError);

function allSuccess(){
  // All calls executed successfully
}

function allError(){
  // At least one of the calls failed
}
