Thanks to an answer from wordpress stack I got this solution:

add this to your functions.php

register_nav_menus(array(
'top-menu' => __('Menu1', 'twentyfourteen'),
'side-menu' => __('Menu2', 'twentyfourteen'),
'footer-menu' => __('Menu3', 'twentyfourteen')
)
);

function my_walker_nav_menu_start_el($item_output, $item, $depth, $args) {
    $menu_locations = get_nav_menu_locations();

    if ( has_term($menu_locations['top-menu'], 'nav_menu', $item) ) {
       $item_output = preg_replace('/

at last you must select the option "Menu1" for the specific menu on which you have to add the anchor custom classes from dashboard Apperance->menus. [select menu2 or menu3 for other menus whose anchor links does not need the custom-class]

To add "active class" to the first menu item of the particular menu then try this one:

function my_walker_nav_menu_start_el($item_output, $item, $depth, $args) {
    $menu_locations = get_nav_menu_locations();


    if ( has_term($menu_locations['top-menu'], 'nav_menu', $item) ) {
       $item_output = preg_replace('/menu_order == 1){
 $item_output = preg_replace('/

if the active class must be added to the first menu item of all menus then use this:

function my_walker_nav_menu_start_el($item_output, $item, $depth, $args) {
    $menu_locations = get_nav_menu_locations();


    if ( has_term($menu_locations['top-menu'], 'nav_menu', $item) ) {
       $item_output = preg_replace('/menu_order == 1){
 $item_output = preg_replace('/
