Answer 1

How about...

{% set names = item.Product_Name|split(',') %}
{% set maxNames = 4 %}

<ul>
    {% for name in names|slice(0, maxNames) %}
        <li>
            {{ name|length < 50 ? name : name|slice(0, 50) ~ '...' }}
        </li>
    {% else %}
        <li>No Results</li>
    {% endfor %}
    {% if names|length > maxNames %}
        <li>More Results Available</li>
    {% endif %}
</ul>

If not then I'm clearly not too sure about what you are actually after.

Also, what is the need for the ,'s in between each name?

If you are wanting something more complex then there is the possibility it should be handled outside of the template and in some kind of twig function.
