Group of fuzes and unknown items

[Infanteer]

I made a group purchase today in order to get a few pieces for my collection and had to take some items that I am not familiar with. First photo is of the entire group and the subsequent photos show the items that I am trying to identify. Any assistance would be appreciated as for some of these items I don't know where to even start.

I only recognize items 13 & 14 as aerial bomb safing pins. WAG on 5-9 is safing clips for aerial bomb prop driven fuzes.

#4 is the firing pin for a British 8 1/2lb and 11lb practice bomb.

first picture upper row, second from left: It could be an incomplete german WW1 K.Z.11 fuze. To be sure, better picture needed.

Thanks for the feedback so far. It's challenging when you don't know where to start but I will now search for aerial bombs to see if that helps.

Yes, it is a K.Z.11 that has some resin type substance at the base and there is a pin protruding from the top. Perhaps someone was trying to make a piece of trench art? Anyway, it's really only the items that are numbered that I'm having difficulty identify but thanks for the feedback.
