Zambia cocoons/pupae for identification

I recently received images of cocoons and pupae from Zambia. Source is looking for id help, and suggests the first three images of cocoons are likley lasiocampidae, possibly Saturniidae, and the last image of four pupae
is probably of Gonimbrasia belina osiris.
Images are posted to

Thanks for having a look.
