Hello,
I had one of 5 drives fail in my raid 5 setup and now many files are
unreadable.. Isn't raid 5 supposed to compensate for exactly this
happening?

It looks like you have multiple drives with problems here:
Here's sde unhappy:

sdb seems to be overheating:

Now sdf is unhappy..

I don't know if this completely explains the failure, but it seems you
have bigger problems than one bad drive, and RAID5 cannot handle
multiple drive failures.

Ahah.. I knew about sdb.. overheating (it's not part of the array) I
missed sde .. that one explains it.
