Explode the items to an array the either foreach as you say or use implode.

$atts['home_blog_id'] ="post:du-an,post:tin-tuc";

$id = $atts['home_blog_id'];
$slug = str_replace( array('post:','post'), array('',''), $id);

echo "<li>" . implode("</li><li>", explode(",", $slug)) . "</li>";
//<li>du-an</li><li>tin-tuc</li>

As Nigel requsted, a foreach version.

foreach(explode(",", $slug) as $val){
    echo "<li>" . $val . "</li>";
}
