Hi @mynetflixtain,
Customers can edit their address information on the “My Account” page.
If you’re looking to provide this capability elsewhere, you’re heading into developer territory, and you’ll want to speak to your developer about that as there’s no shortcode for what you’re looking to do.
Also, I will like to edit some field and change their labels .
If I understand correctly, you’re looking to modify some of the checkout fields. If you’re comfortable working with code, you can follow the directions here – https://woocommerce.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/
Alternately, you can look at the Checkout Field Editor extension, which allows you to do this.
