I am trying to add the script to the particular Product Category page, but the code is not adding it to the category.

Page (working):

function wpb_hook_faq_javascript() {
  if (is_single ('8') || is_page ('8')) { 
    ?>
    <script type="application/ld+json">

    </script>

 <?php }
}
add_action('wp_footer', 'wpb_hook_faq_javascript');

Product Category (not working):

function wpb_hook_faqtocategory_javascript() {
  if ( in_category( 'category-name' )) { 
    ?>
    <script type="application/ld+json">

    </script>

 <?php }
}
add_action('wp_footer', 'wpb_hook_faqtocategory_javascript');

But the above code is not working.

Product Category URL:

wp-admin/term.php?taxonomy=product_cat&tag_ID=9&post_type=product

in_category() should be used inside The Loop (unless if you pass a post ID as the second parameter like in_category( 1, 1 )) and only for the default/built-in category taxonomy.

For custom taxonomies like the product_cat in your case, you should use has_term(); however, if you're checking if the current request/page is a taxonomy archive page, you should instead use is_tax():

function wpb_hook_faqtocategory_javascript() {
    if ( is_tax( 'product_cat', 9 ) ) { // 9 is the term ID, but you can use the slug/name
        ?>
        <script type="application/ld+json">

        </script>
        <?php
    }
}

Or in WooCommerce (you're using WooCommerce, right?), you can use is_product_category(), but you'll need to know the term slug:

function wpb_hook_faqtocategory_javascript() {
    if ( is_product_category( 'term-slug' ) ) {
        // ... your code here ...
    }
}
