Outputting Data Based on Custom Post > Taxonomy

I’m creating a listing of products based on type from custom posts and taxonomies.

I want to create one single template that will output custom posts like this:

———Custom Post Type Template————
GET $Parent_Taxonomy and all $Child_Taxonomies

<h1>$Parent_Taxonomy</h1>

<h2>$Child_Taxonomy1</h2>

<!-- display 4 posts under the child taxonomy -->

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h2>$Child_Taxonomy2</h2>

<!-- display 4 posts under the child taxonomy -->

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>

<h3>$Single_Custom_Post_Title_Based_On_Child_Taxonomy</h3>
<p>$Output_Of_Custom_Meta_Of_Single_Custom_Post</p>
