Answer 1

This code will display all the child categories of selected parent category, tested and works in category.php template file...

$this_category = get_category($cat);
    //echo $this_category->cat_ID;
    $parent_term_id =$this_category->cat_ID; // term id of parent term

//$termchildren = get_terms('category',array('child_of' => $parent_id));
$taxonomies = array( 
    'taxonomy' => 'category'
);

$args = array(
   // 'parent'         => $parent_term_id,
     'child_of'      => $parent_term_id
); 

$terms = get_terms($taxonomies, $args);
if (sizeof($terms)>0)
{

echo ' <div class="categories">  ';     
echo '<p> Sub Categories of '. get_cat_name( $parent_term_id ) .'</p>';

foreach ( $terms as $term ) {

   $term_link = sprintf( '<div class="custom-cats"><a href="%1$s" alt="%2$s">%3$s</a></div>', esc_url( get_category_link( $term->term_id ) ),
        esc_attr( sprintf( 'View all posts in %s', 'textdomain' ), $term->name ),
        esc_html( $term->name ));

    echo sprintf( $term_link );
    }
echo '</div><!-- categories div end-->';
    }
