Couple of changes. First, make sure $scope.alltoys is a collection (array), like this:

$scope.alltoys = [{
  "dId": "570b886545034f0001718247",
  "dName": "Toys",
  "dSubName": "Comics",
  "users": [{
    "name": "Superman",
    "id": "570b9e3a45034f000171827b"
  }, {
    "name": "Batman",
    "id": "570ba00045034f000171828a"
  }]
}, {
  "dId": "5767c68c52faff0001fb8555",
  "dName": "Toys",
  "dSubName": "General",
  "users": [{
    "name": "Jack",
    "id": "570b9e3a45034f000171827b"
  }, {
    "name": "Sparrow",
    "id": "570ba00045034f000171828a"
  }]
}];

Then change your html to handle groups with optgroup, like this:

<select class="form-control" ng-model="toy">
  <option value="">---------------Select---------------</option>
  <optgroup ng-repeat="eachtoy in alltoys | orderBy: 'dName + dSubName" label="{{eachtoy.dName+' - '+eachtoy.dSubName}}">
    <option ng-repeat="user in eachtoy.users | orderBy: 'name'">{{user.name}}</option>
  </optgroup>
</select>

Here's a working plunk
