i have ver 6.0.3.2 can i go back to 5.4.7

I am using ver.6.0.3.2 but you web site says as a casual home user I should use ver. 5.4.7. Can I go back,install 5.4.7 over 6.0.3.2

you web site says…

Where did you find such a statement?

Of course. Please use any version available at Index of /libreoffice/old

But note that current version suitable for conservative users is 6.0.5.

You also could use the old or new or both as portable versions, then you can work anywhere (also on your own PC) with both versions or a particular version. Only don side to portable apps is that they cannot start the program by double clicking the file.
Portable apps are available for Windows, I’m not familiar with other OS’s
