Nicely done!

The abdominal shape of the wasp in #5 is new to me. What is that beast?

It definitely looks like som kind of parasitic wasp (Parazitická vosička) and #4 an #5 are so similar except from the abdomen, that I would suspect they are male and female of the same species. But further identification is a matter for specialists. There are litteraly thousand of species. If we are lucky only a few have this weird shape.

Very nice pictures with good ligthtning and colors.

Maybe it's one of the freakier layouts like some female ichenumons have to oviposit into wood? They contort in a way that feels wrong for a living thing.

Very well done! The tiny wasp looks to be in the family Pteromalidae (5 segmented tarsi being one reason), but there are related families that are possible as far as I know. The families of tiny parasitic wasps are difficult.

Thanks for the suggestion! https://bugguide.net/node/view/390549/bgimage shows an explanation for that strangely shaped abdomen: the ventral bump is where the ovipositor emerges. Apparently the shape is transient during ovipositing -- compare https://bugguide.net/node/view/255026/bgimage versus another view https://bugguide.net/node/view/255024/bgimage of the same individual.
