Answer 1

Maybe your problem is that you are saying you want a .glyphicon icon but in your code you have .fa. fa = font-awesome, not glyphicon.
Try this code:
<div class="form-group has-feedback">
<asp:TextBox ID="txtPassword" runat="server" CssClass="form-control" TextMode="Password" placeholder="Password"></asp:TextBox>
<span class="glyphicon glyphicon-asterisk form-control-feedback"></span>
</div>

First, you're probably using the incorrect class and HTML element. fa and fa-calendar are font-awesome classes to add those icons. You want to use glyphicon and glyphicon-calendar in your HTML <span> class as well.
Second, you could use a wrapper and some CSS to achieve this. See the snippet below:
.input-wrapper {
border: 1px solid #ccc;
position: relative;
padding-left: 20px;
}
.input-wrapper input { // Remove the borders
border: none;
outline: none;
border: none !important;
-webkit-box-shadow: none !important;
-moz-box-shadow: none !important;
box-shadow: none !important;
}
.input-wrapper span.glyphicon {
position: absolute;
top: 10px;
left: 10px;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="col-xs-6 date-range form-group has-feedback" id="date_range">
<div class="input-wrapper">
<span class="glyphicon glyphicon-calendar" aria-hidden="true"></span>
<input name="daterange" class="form-control">
</div>
</div>
