How do I add my own 'Nether'?

On the worlds tab, click "upload" on the nether, and select your Nether folder

I only found the world file with 4 options: Download, Upload, Generate and Files. Do I click on "Upload" and if I choose world_nether it will upload the nether without replacing the world itself?

No There Are Worlds Like World_nether World_The_end

I know, but how can I upload it?

First go to https://aternos.org/worlds/ . Then , find "World_Nether" there (you should have that if your server is vanilla 1.16.1/1.16.2)

After that you'll see a orange "upload" button there. Click on it and choose folder or zip archive according to what file type you want to upload.

Also , take a look at this article . There's a detailed tutorial on uploading worlds to your server

That's the problem. I think the reason is that I uploaded this world

Hmmm.... is your server using vanilla 1.16.1 ?

I see this for my 1.16.1 server:

Maybe you can try starting the server once and check if the server generated the world_nether file when starting server. If it generated the world_nether file , then you will be able to see it and add your own nether to the server.

You have a bukkit server.
