Answer 1

In your <fieldset> section you could use <insertListing>.

    <fieldset name="assign_applicants">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="label" xsi:type="string" translate="true">Applicants</item>
                <item name="collapsible" xsi:type="boolean">true</item>
                <item name="sortOrder" xsi:type="number">30</item>
            </item>
        </argument>
        <insertListing>
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="autoRender" xsi:type="boolean">true</item>
                    <item name="ns" xsi:type="string">applicants_form_listing</item>
                </item>
            </argument>
        </insertListing>
    </fieldset>

In the ns config you specify the listing UI component's name. Then you define this component separately in the view/adminhtml/ui_component/applicants_form_listing.xml and describe what should be in the grid (you can check this thread for details).
