</div>
<!--/.container -->
</section>
CSS
.col-md-6.map { margin-left: -15px; }
.form-horizontal { width: 100%; float: right; }
.form-group { margin-bottom: -25px; }
.col-md-6.form { border: 1px solid red !important; }

Answer 1

Add col-md-offset-2
<div class="form-group">
// place col-md-offset-2 here for each input
<div class="col-sm-10 col-md-offset-2">
<input type="text" class="form-control" id="name" name="name" placeholder="Vorname, Name" value="">
</div>
</div>

Answer 2

inside form-group either change col-sm-10 to col-sm-12 that will make your input fields take entire width of your form or if yo want them right aligned give float:right to your col-sm-10 div it will work

Answer 3

Not sure what you really want, but if you want the whole form being at the extrem right of the screen, you have to remove the fixed width of your div class="container" which is the reason you have white space on right side.
If you want input being on the right side of your red-bordered area, you should put "float:right" on the col-sm-10" class. Hope it helped you
