You could use the Essentials plugin and use /setwarp <warp name> in different worlds, and use Multiverse-Core to create/teleport to different worlds.

I am making a server right now, and I have a lobby world, but I want to create warps to different worlds, of which, I already have uploaded to the server panel. How can I do this?

The developers are still working on getting some Minehut servers back online. If your issue doesn't resolve within the next few days, I'd recommend reaching out to support at https://minehut.com/support, they should be able to fix it.
