Can I safely delete some Photoshop, CC, & Bridge folders

[AllNikons]

Need to free up space on my hard drive. In reviewing program folders, I see the following Adobe folders:

Adobe Photoshop CC 2018  8/13/2019

Adobe Photoshop CC 2017  10/18/2017

Adobe Photoshop CC 2015.5  12/1/2016

Adobe Photoshop CC 2015  6/21/2016

Adobe Photoshop  2020       2/19/2020

Adobe Creative Cloud Experience  2/26/2020

Adobe Creative Cloud  2/11/2020

Adobe Bridge CC 2017  10/18/2017

Adobe Bridge 2020  2/11/2020

I would think I could delete all folders EXCEPT the lastest Photoshop (2/19/2020), Creative Cloud (2/11/2020), and Bridge (2/11/2020).  Is that correct? Obviously this would free up a lot of disk space, but I certainly don't want any "unanticipated consequences"  (disasters). Can I safely remove the old folders?

If this is a Teams or Enterprise Account, contact your IT dept for assistance.

If this is an individual account, you can uninstall old versions from your CC Desktop App.  But I usually uninstall through my operating system.  

Keep in mind that Adobe's new version policy means you can't get older (pre-2019) versions anymore.  So before you  remove an old version, make sure you don't need it.  Once they're gone, it's almost impossible to get them back again.
