First is a species of sawfly (Hymenopteran not a true fly), then Dark Bush-cricket nymph + finally a hawker dragonfly nymph.
 
The abdomen pattern is most important for Rhogogaster species, so it is very lucky that you found it with missing wings (not so lucky for the sawfly, mind you). Certainly viridis is one of the few species with a black central abdomen, and it occurs throughout. It may be the only UK species like this.
 
I'm no expert but from what I understand, the green pterostigma are more likely to make it a Rhogogaster (correct spelling) than a Tenthredo - but please correct me if that's not the case.

More likely yes but that is because the green "Tenthredo" with black pterostigma (mesomelas) is common and widespread while its close congeners with green pterostigma are scarce and predominantly northern.
