Have you tried 
cd <effected directory>
sudo chmod -S xs_colors.h
sudo chmod -s xs_yarandom.h
sudo chmod -S xs_hsv.c

then rm -f <filename>

or even
sudo erase <effected directory>>

It's odd that the current and parent indicators also have those
permissions (s and t bits set)
As an aside, try strings on any of those files. If they aren't what they
should be (which is 'C' source code), I'd have a serious talk with your
'friend' ...
