Hi,
There is not the default options to add more than 4 images in one row in Gallery Layout Builder.
Maybe you can enter HTML code in text box:

<div class="row">
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
<span class="col-lg-2"><img src="http://xxx.com***.jpg"></span>
</div>
It needs some custom css also:
.list-layout-text {
padding: 20px 0;
}
.list-layout-text img {
max-width: 100%;
}
Regards!
