Removing rel=”nofollow” from links posted in Post Content

These links are generated by alx_social_links() function.
So in your theme’s functions.php file, search for alx_social_links() function and this link specifically.

echo '<li><a rel="nofollow" class="social-tooltip" '.$title.' '.$link.' '.$target.'><i '.$icon.' '.$color.'></i></a></li>';

and remove rel="nofollow" from it. So this will be the new link.

echo '<li><a class="social-tooltip" '.$title.' '.$link.' '.$target.'><i '.$icon.' '.$color.'></i></a></li>';

It will remove nofollow tag from these links.
