Answer 1

You just need to use on order-md-0 order-last the navbarcollapse so that it is positioned last on mobile screen widths (when the Navbar is collapsed)...
<div class="collapse navbar-collapse order-md-0 order-last" id="navbar4">
<ul class="navbar-nav ml-auto">
<li class="nav-item bg-white border-success"> <a class="nav-link" href="#">Features</a> </li>
<li class="nav-item"> <a class="nav-link" href="#">Pricing</a> </li>
<li class="nav-item"> <a class="nav-link" href="#">About</a> </li>
<li class="nav-item"> <a class="nav-link" href="#">FAQ</a> </li>
</ul>
</div>

Answer 2

The container inside the navbar is a flex having justify-content: space-between, Hence navbar-collpase which is initially hidden gets displayed on toggle gets pushed below.
Solution:
Making the navbar-collpase positioned absolute to the navbar will fix the problem.
Example:
#media only screen and (max-width: 600px) {
.navbar-collapse{
position: absolute;
width: 100%;
top: 56px; /*height of navbar in mobile*/
}
}
