I want to have different customizations on different desktops, example one that looks like Windows and another that looks like Mac. How can I do that? (without creating a new user)

Activities, and removing the stock panel, and replace it with Latte Dock, so each one can have unique dock/panel setups.

but can I have different icons or is it only possible to have different panels?

Yes - different desktop widgets, different Favorites in the menu, different backgrounds, and of course unique docks and/or panels (if you use Latte Dock)

Here are shots of some of mine

The bottom one I quickly slapped together, and didn't add any application icons, just a few widgets, I don't normally have any desktop icons anywhere, and only use widgets on some activities.
