As with most extensions you can disable or uninstall anything you are not using.
Because we do not know what you are using and what is installed we cannot give much advise
My suggestion is to take a backup and install it elsewhere. On the copy site just disable one RT extension and check that all of site works properly. If all is working disable the next. If the site breaks at any point then enable th last extension you disabled.
Do this until you have all unrequired extensions disabled. At this stage you can safely try uninstalling the unpublished ones.
If this resolves your problem then please edit your first post in this thread by adding SOLVED at the start of the title and then select the green tick icon. This lets the moderators know that it can be moved to the solved section.
Thanks for your cooperation
