Yes, other addresses should be fine, as long as they were created independently and have their own PK.
As a security, it might be worth moving any assets to "fresh" wallets just in case, if someone had access to one PK, it's possible they had access to more (especially if you copy and paste on a computer, lots of programs that can track this data for hackers if you have some bugs on your computer).
I see. Thank you :)
time for some cleaning
