Load Posts on Click via Ajax into a DIV

The short answer to your question is simply, yes it is possible. It involves code across JS and PHP and is beyond what I would be able to show in an answer here. However I did a simple Google search for “wordpress load posts with ajax” and this link is the first result. https://wpmudev.com/blog/load-posts-ajax/ I scanned through the tutorial and it appears to be very detailed and I believe it should help you get where you need to be.
