PRP gives good advice on this. I would not touch those files.
Anything in private/var is meant to not be disturbed by the user. They are not active but instead provide a history of what was installed. You can probably delete them but it will require changing permissions and some other invasive steps and unless the folders are restored as they were, there could be trouble that results. There is no need to take risks.
The files you found in PrivateFrameworks also need not be touched. They have information about fonts associated with the Adobe software that you removed. So there is nothing negative that will result from leaving them as they are. Again, you can get access to delete them but it might require changes to permissions and that could entail risks unless you know exactly how you are proceeding.
I think if you actually do delete those files nothing bad will result. After all, they are from an uninstalled program. But if you adopt the philosophy of "first do no harm," I would just leave them where they are. They are taking virtually no disk space.
