The attached bugs and butterfly were observed in Andasibe National Park Madagascar. We have been unable to gain a positive identification for any of them.
No interactions present.
Your top left image looks to me like a caddis fly larva emerging from its shelter; was it from a pond or- possibly - from a rather wet, ostensibly terrestrial environment?
Your third image strikes me as a weevil, slightly similar to, but not that close, to the Figwort Weevil, that MickETalbot has posted a few items back. Do you know what its food plant was? The fourth creature (bottom left) is almost certainly a true bug (Shieldbug). (True) bugs are characterized by a sucking rostrum (beak) which is often held closely under the body and thus difficult to see. Even with that proviso, I can’t see one under your fifth insect (bottom right). So, I think it is probably not a “true bug” but something else.
