Is it possible to make something using 2 or more html files using ui-view? I need it to be something like this :

I've tryed to do something working on plinker, but looks like I clearly don't uderstand concepts. I've read a nested ui-vew tutorial but they simple make a single index.html and place multiple ui-view there, but I need multiple .html files.
test.html is just a file with some text that should be displayed under master header
index.html looks like this
<html ng-app="MyApp">
<head>
  <link href="stylesheets/style.css" rel="stylesheet">
</head>
<body>
<h4>
    This should be Master  header
</h4>
<div ui-view></div>
<script data-require="angular.js@*" data-semver="1.3.0-beta.5" src="https://code.angularjs.org/1.3.0-beta.5/angular.js"></script>
<script data-require="ui-router@*" data-semver="0.2.10" src="https://rawgit.com/angular-ui/ui-router/0.2.10/release/angular-ui-router.js"></script>
<script src="app.js"></script>
<script src="controllers/main.js"></script>
</body>
</html>
this is app.html
<head>
  <link href="stylesheets/style.css" rel="stylesheet">
</head>
<body>
<h4>
    This should be Sub  master header 
</h4>
<div ui-view></div>
</body>
and app.js is written on pseudo code showing how I want it to work, because I clearly have no idea how to make it work
    angular.module('MyApp', [
  'ui.router'
])
.config(function($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise('/');
    $stateProvider
        .state('index', {
            templateUrl: 'index.html',
            controller: 'IndexCtrl'
          })
        .state('index.test', {
            url: '/',
            templateUrl: 'test.html',
            controller: 'TestCtrl'
          })
        .state('app', {
            templateUrl: 'app.html',
            controller: 'AppController'
          })
        .state('app.test2', {
            url: '/test2',
            templateUrl: 'test2.html',
            controller: 'Test2Controller'
          })
})
test2.html is just a text.
