Hey @kefka750, thanks for posting your question to our Community and happy Friday!
When it comes to shared folders/files, the members with edit permissions will be able to see each other's names.
If you want to keep them private, what you could do is create a folder and inside that folder, create multiple subfolders, which will include the files you want to share and share those subfolders individually with each user.
That way, they won't see each other, however, keep in mind that these will be different files, so they won't be able to see each other's edits on the file.
Each shared file will have each user's edits only.
I hope this clarifies things, but let me know if you have any questions.
