If it appears there is more than one species involved, please make it separate threads. Easier to keep an overview, then.

Top could be Hercostomus s.l.
Middle: Poecilobothrus nobilitatus, easily recognised by those darkened wings with white tips.
Bottom might be the female of the same species.

Thank you Paul.
The middle and bottom image were taken at the same time. I noted that many males were displaying to the females and this suggests the bottom image is of the same species as the middle image.
I understand you comments re mixed species and will re-post the first one as you suggest.

I thought that this image may be of interest, it is the Water Measurer (Hydrometra stagnorum) feeding on Poecilobothrus nobilitatus which had allowed itself to get too close.

I hope this did not break any of the rules on here.
