Bit difficult to see from the pics, but I agree the first one I think is an adult Chironomid ('buzzer') - you can usually tell by the two 'fans' on their face and
they have a thin body but no 'sting'.
I think the fatter black jobs are adult blackflies ('Simulium' family). These are the guys with conical shaped larvae and thew adults bite like buggery - especially if you're wearing a blue shirt
The caddis seems to be one of the Hydropsychidae adults. The larvae being the 'mustard caddis' jobbies. These usually stick around the river a bit later in the season than the Macrostemum ('chartreuse caddis' larvae) adults which are a bit larger and paler and more of a summertime occurrence.
What's on the one pic I can't tell as all I see is camouflage!!!
