This is a datapack, it can easily be used in any world or server without any difficulties.
Simply drop the downloaded zip file in the "datapacks" folder of your world save (<world>/datapacks).
Then open your world and do
/reload

In case the datapack doesn't automatically get enabled, run:
/datapack enable "file/[​datapack folder name].zip"

I don't know, unfortunately I can't check all of my submissions on each version out there. Have a look at the bottom of the submission for the known compatible versions. You're free to try the data pack in versions that are not specified with the risk of it not working. If it does work, let me know in the comments so I can adjust the listed known compatible versions.

I test all my creations, but bugs happen no matter how long you test something. Whenever someone experiences a bug, I do my best to fix the issue. You can help me by providing any useful information. You can never give me enough information, but please send it in a DM instead of placing it in the comments. You can still place a one-liner in the comments stating the issue to make the community aware, but that alone isn't enough to help me fix the issue.

• Checklist: Are you using the right version? Did you do /reload after dropping the datapack in? After /reload, does the datapack show up green in /datapack list?
  
• What is the issue? Does the datapack not seem to be working at all or is there a specific feature you are having issues with?
  
• What happened? Please give me all the steps needed to reproduce the issue. The faster I can experience it, the faster I can solve it.
  
• What did you expect to happen instead? This helps me understand your point of view and determine if the issue described is actually the issue I need to fix. The bug you are experiencing could just be a side effect of something else that doesn't behave as expected.
