I guess not as this is not working:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" >
$("p:after").addClass("allgone");
</script>
<style type="text/css">
p:after {
content: "daniel";
}
.allgone{
display: none;
}
</style>
<title></title>
</head>
<body>
<p></p>
</body>
</html>

There are no special rules around combining pseudo-classes and pseudo-elements, besides the one rule that says there can only be one pseudo-element per complex selector and it must appear at the very end.
If you're talking about pseudo-classes, then yes, you can combine them in any order.
In CSS, ::before creates a pseudo-element that is the first child of the selected element. It is often used to add cosmetic content to an element with the content property. It is inline by default.
Multiple pseudo-elements can be created with the ::before(ordinal) and ::after(ordinal) notation, where 'ordinal' is a positive integer. ::before pseudo-elements are ordered descending by 'ordinal' from the host element's content edge.
No, but you can add the class to the p element, and create an alternate style for it.
p:after {
content: "daniel";
}
p.allgone:after {
display: none;
}
$('p').addClass('allgone');

No, pseudo elements are not part of the DOM, and they can not be accessed via JavaScript.
I believe they are part of the Shadow DOM. The pseudo element is rendered by the browser as an inline element inside of the containing element, either as the first or last child.
