Answer 1

I would change it like this:

<header class="header">
  <div class="header_wrapper">
    <nav class="nav nav-header">
      <li class="nav__item">Первая</li>
      <li class="nav__item">Вторя</li>
      <li class="nav__item">Третья</li>
      <li class="nav__item">Четвертая</li>
      <li class="nav__item">Пятая</li>
      <li class="nav__item">Шестая</li>
    </nav>
  </div>
</header>
