How to add additional “checkout” button next to “add to cart” button in product page in woocommerce?
I added a woocommerce folder into my childe theme in order to modify single-product => add-to-cart => simple.php
Inside simple.php I found the standard "Add to cart" button and after it is where I want to add my custom additional "checkout" button
I used this code

function woo_redirect_to_checkout() {
    $checkout_url = WC()->cart->get_checkout_url();
    return $checkout_url;
}

This is working but modifying all "add to cart" buttons in the site and I am trying to add it ONLY to the new custom button. Can anyone tell me how do I add a NEW button + this button needs to not only go to the checkout page but also trigger the "Add to cart" action at the same time

You need to use the WooCommerce hook woocommerce_after_add_to_cart_button. It will add content after the "Add to cart" button.
Also, a product can be added to the cart with a link like this
http://example.com/cart/?add-to-cart=<product ID>
Using both that is above the hook and this link, you can add a second button with this snippet:

function add_content_after_addtocart() {

    // get the current post/product ID
    $current_product_id = get_the_ID();

    // get the product based on the ID
    $product = wc_get_product( $current_product_id );

    // get the "Checkout Page" URL
    $checkout_url = WC()->cart->get_checkout_url();

    // run only on simple products
    if( $product->is_type( 'simple' ) ){
        echo '<a href="'.$checkout_url.'?add-to-cart='.$current_product_id.'" class="single_add_to_cart_button button alt">Checkout</a>';
    }
}
add_action( 'woocommerce_after_add_to_cart_button', 'add_content_after_addtocart' );

It will add a button after the normal Add to cart button on single product pages.
