    This can be done with small customization. If you want to insert this validation on single line text field type. You can edit "includes/post-functions.php" file and go to around line 191 for this code :

    $rules[$element_name]['max'] 		= 255;

    Then add these code bellow that line

    if ($form_id == 22 && $element_id == 1) {
    	$rules[$element_name]['min'] 		= 5;
    }

    In there I assume your form id is 22 and the single line text field element id is 1. You need to change those id with yours.

    What is the proper syntax for the name field element where it is a multi element field...I've tried '_1' and it does not do anything (doesn't break the code but doesn't enforce the rule)

    You need to put the custom code on different line number for simple name field. Try to go around line 322 on post-functions.php. You will see these code :

    $target_input[$element_name]   = $user_input[$element_name];

    then you can add this code, exactly above that line

    if ($form_id == 22 && $element_name == 'element_1_1') {
    	$rules[$element_name]['min'] = 1;
    }
    
    if ($form_id == 22 && $element_name_2 == 'element_1_2') {
    	$rules[$element_name_2]['min'] = 7;
    }

    that would make you need to put at least 1 character for first name and 7 characters for last name.
