Answer 1

You can use the flexbox property to achieve what you want and set the image as background.
body, html {
margin: 0;
padding: 0;
color: white;
}
.container {
height: 767px;
display: flex;
}
.left {
background-image: url('http://i.imgur.com/AzeiaRY.jpg');
background-size: cover;
flex: 1;
}
.right {
display: flex;
flex-direction: column;
flex: 0 0 50%;
}
.one {
background-image: url('http://i.imgur.com/AzeiaRY.jpg');
background-size: cover;
flex: 50%;
}
.two {
background-image: url('http://i.imgur.com/AzeiaRY.jpg');
background-size: cover;
flex: 50%;
}
<div class="container">
<div class="left">Left image</div>
<div class="right">
<div class="one">First image</div>
<div class="two">Second image</div>
</div>
</div>

In Bootstrap 5, you can use d-grid gap-x. For example:
HTML
.content {
background-color: transparent;}
.content .left, .content .right {
float: left;}
.full-width-band-hd {
margin-top: -35px;}
.txt-yellow {
color: var(--bs-yellow);}
<section class="container-lg">
<div class="content row">
<h2 class="txt-yellow full-width-band-hd">Head</h2>
<!-- Left Side -->
<h6 class="text-yellow">H6 head</h6>
<h3 class="text-yellow">H3 head</h3>
</div>
<!-- style in content row will become a class later-->
<div class="content row" style="height: 642px;">
<div class="col-md-4 left d-grid gap-3">
<div class="">
<img src="image1" width="100%" height="auto" alt="fp1">
</div>
<div class="">
<img src="image2" width="100%" height="auto" alt="fp2">
</div>
</div>
<!-- End of Left Side -->
<div class="col-md-8 left">
<div class="">
<img src="image3" width="100%" height="auto" alt="fp3">
</div>
</div>
<!-- End of col-md-8 -->
</div><!-- content row -->
</section>

Answer 3

You should format your code like below:
<div class="row">
<div class="col-md-8">
<img class="img-big img-responsive" src="https://en.apkshki.com/storage/5/icon_5dcfce7f86906_5_w256.png"></div>
</div>
<div class="col-md-4">
<img src="https://en.apkshki.com/storage/5/icon_5dcfce7f86906_5_w256.png"></div>
<img src="https://en.apkshki.com/storage/5/icon_5dcfce7f86906_5_w256.png"></div>
</div>
</div>
As you can see the two images at the bottom in col-md-4 if you spread the width 100% the next image will drop below.
You shouldnt really have a class with both a row and a col-md in the class name. (See http://getbootstrap.com/css/)
With regards to reducing the height and not the width are you not able to crop the image down on Paint or Photoshop and upload the image with the correct height?
