I currently use a 5$ Droplet to host a Wordpress website, today about 20 people loaded in to my in about a minute, and the server crashed. What can I do to prevent this from happening again?

You're running out of RAM, so you need to upgrade your droplet. A $10 plan should suffice, but it all depends on the setup of the server and how many plugins/themes you're running.
I'm using the theme Parallax One and about 10 plugins. So the 10$ Droplet would fix this? Thank you so much for the answer by the way!
I would recommend that you install the DigitalOcean monitoring agent, which will help you have an overview of the resources used on your server:

Parallax One is a little heavy, but in general it's the plugins that can consume a lot of memory and it depends on the specific plugin (not the number of plugins). Meaning you can have one plugin, which uses massive amounts of CPU and RAM.
But a wrongly configured MySQL can easily eat all your RAM within a couple of seconds, if a plugin does a huge query.
