Answer 1

The functions look pretty accurate to me. Are you sure they aren't updating? Or perhaps you are having difficulty is displaying them.

I've tweaked them a bit. First, to use the $posted variabled that WooCommerce sends to the function, though this is trivial as $_POST should be the same. And secondly, you are using esc_attr() when you should be using sanitize_text_field() . The former is for displaying the data in an HTML attribute while the latter is for sanitizing before saving.

//* Update the order meta with field value
//**/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta', 10, 2 );

function my_custom_checkout_field_update_order_meta( $order_id, $posted ) {
    if ( isset( $posted['Account'] ) ){
        update_post_meta( $order_id, 'Account', sanitize_text_field( $posted['Account'] ) );
    }
}

/**
* Update the user meta with field value
**/
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta', 10, 2 );
function my_custom_checkout_field_update_user_meta( $user_id, $posted ) {
    if ( $user_id && isset( $posted['Account'] ) ){
        update_user_meta( $user_id, 'Account', sanitize_text_field( $posted['Account'] ) );
    } 
}
