From what I can see this can all be done with one set of punches on a simple fly press, google fly press.
If the male and female have the bend shape in your last picture, bottom right but also the outline shape of the part the flypress with first cut it, then bend it and a set of spring loaded pins will finally punch the holes.
Ejection springs are needed to obviously eject the part ready for the next item.John S -

Right ok, thanks John. I see what your saying, if I maybe redesigned the
cutting die so that it cuts, punches the holes and bends the shape at
the same time. Good plan. Fly presses look awfully expensive, well outside
my budget, I was hoping to accomplish all this by banging on a mild steel
plate to create the force necessary for the cutting and punching etc.
I am a chainmail armour crafter. I like to keep it simple and bang on
things with a hammer to get a result.
I was not sure if I could generate enough force to cut out the shape
and do the punches at the same time, which is why I seperated them
into individual processes.
