Nozzle settings

I have an Ender 3 - v3, not SE/KE. I have bought three new Nozzles, 0.2, 0.6, & 0.8.
My question is, in the slicer, when I go to create the new printer, I get several errors in the process screen related to line width. Can someone please tell me what the correct settings are for these three different nozzles?

In particular, the 0.2, when I select it, it throws up lots of errors.

Another post says to use the Orca slicer settings,0.6 can you export this or do you install the settings manually

Thanks in advance
