add the ng-repeat1 like this withdate` filter

<ul ng-repeat="item in arr.messages">

 <li>
     {{item.u.username}}
 </li>
 <li>
     {{item.ts  | date : 'yyyy-M-d'}}
 </li>
 </ul>

angular.module("app",[])
.controller("ctrl",function($scope){
$scope.arr = {
  "messages": [
    {
      "_id": "sdfsdfsd",
      "t": "subscription-role-removed",
      "rid": "sdfsfsfd",
      "ts": "2017-05-10T07:03:26.865Z",
      "msg": "samim",
      "u": {
        "_id": "sdfdsf",
        "username": "dsdfsfsd"
      },
      "groupable": false,
      "role": "moderator",

Answer 2

ng-repeat is actually what you want here. and for date formatting, you can use date filter.

refer below example.

angular.module("app", [])
  .controller("myCtrl", function($scope) {
    $scope.data = {
      "messages": [{
          "_id": "sdfsdfsd",
          "t": "subscription-role-removed",
          "rid": "sdfsfsfd",
          "ts": "2017-05-10T07:03:26.865Z",
          "msg": "samim",
          "u": {
            "_id": "sdfdsf",
            "username": "dsdfsfsd"
          },
          "groupable": false,
          "role": "moderator",
          "_updatedAt": "2017-05-10T07:03:26.865Z"
        },
        {
          "_id": "sdfsdfsdfssd",
          "t": "subscription-role-added",
          "rid": "asdafdaf",
          "ts": "2017-05-10T06:51:23.147Z",
          "msg": "samim",
          "u": {
            "_id": "ssdfsdf",
            "username": "adfffffsfmin"
          },
          "groupable": false,
          "role": "moderator",
          "_updatedAt": "2017-05-10T06:51:23.147Z"
        },
        {
          "_id": "fafasfasf",
          "t": "au",
          "rid": "sdfsdfsfsdf",
          "ts": "2017-05-10T06:50:14.029Z",

          "groupable": false,
          "_updatedAt": "2017-05-10T06:50:14.036Z"
        },
        {
          "_id": "sfdsfsdfsd",
          "rid": "sfsdfsdfs",
          "msg": "hi",
          "ts": "2017-05-10T06:44:27.610Z",
          "u": {
