Answer 1

Assuming you want the default columns to have width 4, like col-md-4, I can suggest the following approach:
Do not specify column width in the HTML and justify the content evenly:
<div class="container">
<div class="d-flex justify-content-evenly row">
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">One</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Two</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Three</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Four</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Five</div>
</div>
</div>
</div>
</div>
</div>
Then set the minimum size of all columns:
.my-2 {
flex-basis: 33.3%;
min-width: 33.3%;
}

Use equal-width utility of bootstrap. Divide the area in 2 rows with same width (col-md-8 here) and then place as many divs of equal width.
Sample below:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
<div class="d-flex justify-content-around row">
<!-- row-1 -->
<div class="row col-md-8">
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">One</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Two</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Three</div>
</div>
</div>
</div>
</div>
<!-- row-2 -->
<div class="row col-md-8">
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Four</div>
</div>
</div>
</div>
<div class="my-2 col">
<div class="card">
<div class="card-body">
<div class="card-title">Five</div>
</div>
</div>
</div>
</div>
</div>

Answer 3

You can create using 'Equal-width', for more details go through the Bootstrap 4 Grid System.

Answer 4

Bootstrap comes up with a lot of different solutions to achieve multiple views. What you've been trying so far was almost correct. However, your last col ist currently just looking a bit wrong. You might exchange your last cols classes by the following.
<div class="my-2 col flex-grow">
This does simply 2 things.
Using col you're letting flexbox decide how much space to take
Adding flex-grow you're telling flexbox to use and fill up any left space
