How Do I Enqueue a Script into 2 different Footers on the Same Site?

While get_footer('name_template_file'); includes the defined footer template it does not output WordPress wp_enqueued styles and scripts that are defined to be output in the footer automatically. To let your page output all javascript files and stylesheets that supposed to go to the footer call <?php wp_footer(); ?> at the place you want them to be rendered.
You could consider to place them in you main template (directly before </body> so there is no need to put them in every single footer template you might include. In most cases it should work fine.
