Answer 1

You need to use a foreach loop with order items from a dynamic Order ID $order_id (or from the WC_Order object $order):

// Get an instance of the WC_Order object (if you don't have the WC_Order object yet)
$order = wc_get_order( $order_id );

// Loop through order items
foreach( $order->get_items() as $item_id => $item ) { 
    // Get an instance of the WC_Product Object
    $product = $item->get_product();

    // Get the product ID
    $product_id = $product->get_id();

    // Get the item quantity
    $quantity = $item->get_quantity();
}
