Help identifying a few African currency knives/blades

[wildwolberine]

I recently acquired this small collection of African iron currency knives. I’ve tentatively identified a few. Would appreciate any input from specialists in this field! I do not have any information from the previous owner.

I believe the curved knife on the left is Ngbaka, the angular “hoe” is Idoma (Nigeria), the long sickle with a socket handle is Kirdi (Cameroon). Not sure about the small spear shaped item, the smaller sickle shaped item, the bell, or the throwing knife (very thin and flexible).
