Rename multiple order statuses in Woocommerce

Question

I'm trying to rename multiple WooCommerce order status by editing my theme's functions.php file. I found some code posted here a couple years ago that works to change a single order status, but since I'm very inexperienced with php, I don't know how to expand on it to change multiple statuses. Ideally I'd also like to rename 'wc-processing' to 'Paid' and 'wc-on-hold' to 'Pending'.

Here's the code I found to edit a single order status:

function wc_renaming_order_status( $order_statuses ) {
    foreach ( $order_statuses as $key => $status ) {
        $new_order_statuses[ $key ] = $status;
        if ( 'wc-completed' === $key ) {
            $order_statuses['wc-completed'] = _x( 'Order Received', 'Order status', 'woocommerce' );
        }
    }
    return $order_statuses;
}
add_filter( 'wc_order_statuses', 'wc_renaming_order_status' );

Anyone know what changes I need to make to change additional statuses?

As Pending order status exist, you need also to rename the existing "Pending" status. If not you will get 2 different statuses with the same "Pending" label.

First to rename those order statuses:

add_filter( 'wc_order_statuses', 'rename_order_statuses', 20, 1 );
function rename_order_statuses( $order_statuses ) {
    $order_statuses['wc-completed']  = _x( 'Order Received', 'Order status', 'woocommerce' );
    $order_statuses['wc-processing'] = _x( 'Paid', 'Order status', 'woocommerce' );
    $order_statuses['wc-on-hold']    = _x( 'Pending', 'Order status', 'woocommerce' );
    $order_statuses['wc-pending']    = _x( 'Waiting', 'Order status', 'woocommerce' );

    return $order_statuses;
}

And Also in the bulk edit order list dropdown:

add_filter( 'bulk_actions-edit-shop_order', 'custom_dropdown_bulk_actions_shop_order', 20, 1 );
function custom_dropdown_bulk_actions_shop_order( $actions ) {
    $actions['mark_processing'] = __( 'Mark paid', 'woocommerce' );
    $actions['mark_on-hold']    = __( 'Mark pending', 'woocommerce' );
    $actions['mark_completed']  = __( 'Mark order received', 'woocommerce' );

    return $actions;
}

And also this is needed (for the top menu):

foreach( array( 'post', 'shop_order' ) as $hook )
    add_filter( "views_edit-$hook", 'shop_order_modified_views' );

function shop_order_modified_views( $views ){
    if( isset( $views['wc-completed'] ) )
        $views['wc-completed'] = str_replace( 'Completed', __( 'Order Received', 'woocommerce'), $views['wc-completed'] );

    if( isset( $views['wc-processing'] ) )
        $views['wc-processing'] = str_replace( 'Processing', __( 'Paid', 'woocommerce'), $views['wc-processing'] );

    if( isset( $views['wc-on-hold'] ) )
        $views['wc-on-hold'] = str_replace( 'On hold', __( 'Pending', 'woocommerce'), $views['wc-on-hold'] );

    if( isset( $views['wc-pending'] ) )
        $views['wc-pending'] = str_replace( 'Pending', __( 'Stucked', 'woocommerce'), $views['wc-pending'] );

    return $views;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
