in short then

public function rules()
    {
        return [
            ['login', 'validateLogin'],
        ];
    }

    public function validateLogin($attribute, $params, $validator)
    {
        if (!is_telephone($this->$attribute) && !is_email($this->$attribute) && !is_name($this->$attribute)) {
            $this->addError($attribute, 'Должен быть емейлом, телефоном или именем');
        }

PS
is_telephone, is_email, is_name
Your custom functions (maybe methods) for validation
