Hello Kalise10,
Thanks for using our theme. As per your questions, this features is not available on our themes. You can change the number of post to show there, you have to customize the theme. You will find that codes on acmethemes/sidebar-widget/acme-col-post.php file. You can change the number of code from there.
In case of adding load more,it is somehow complex for integrating this feature. So, please hire a customizer. I will be best for you. http://www.acmethemes.com/customization-request/
Thanks
