I'm pretty sure the walnuts would be rancid and probably the filberts too. The wheat germ would be iffy. The Quick Oats, coconut and graham wafer crumbs should be okay as long as there's nothing moving in them.
As far as I know the white stuff on chocolate is called bloom and not a problem at all if appearance doesn't matter so close your eyes when you eat them.
Except for the nuts, which need to be tossed, and of course the chocolate, I have no idea if any of the other stuff is okay to feed birds.
