According to AngularJS website, Only one AngularJS application can be auto-bootstrapped per HTML document. Ng-app API document.

To fixed your issue, you only allow to have one ng-app for one html document. In this case, either you declare ng-app = "app" in body tag or in html tag. And then assign controller to different div tag.

HTML

<body ng-app="app">
  <div ng-controller="lots">
    <h3>Comparatif des lots en volume</h3>
    <canvas id="doughnut" class="chart chart-doughnut"
            chart-data="data" chart-labels="labels" height="100px" 
            chart-legend="legend">
    </canvas>           
  </div>
  <div ng-controller="repartition">
    <h3>Répartition des différents types</h3>
    <canvas id="doughnut2" class="chart chart-doughnut" 
            chart-data="data" chart-labels="labels" height="100px" 
            chart-legend="legend">
    </canvas> 
  </div>
</body>

JS

angular.module("app", ["chart.js"])
       .controller("lots", function ($scope) {
           $scope.labels = ["Non lotis", "Lot 1", "Lot 2"];
           $scope.data = [90, 5, 5];
        })
       .controller("repartition", function ($scope) {
           $scope.labels = ["JCL", "Appli", "Copy", "Mapset", "PGM"];
           $scope.data = [80, 2, 3, 0.5, 10];
        });
