You must have to pass correct hook name after,
The Hook must be end with the name of action you are passing through jQuery request ex.
wp_ajax_nopriv_{action_name} so please correct it first.
add_action( 'wp_ajax_nopriv_ajax_login', 'ajax_login' );
Put this action outside the function and do your login condition inside the hook callback function.
function ajax_login(){
if (!is_user_logged_in()) { // It's not necessary it should be based on your requirement
// Your code goes here.
}
}
