For sheet metal punching you will have in mind:
Material
Thickness of sheet metal
And punching size
You will need a punch of diam 9mm and 6 mm, and below you will need a die with almost 1mm of clearance (based on mild steel clearance chart)
this will help you with cutting clearance
For cut this metal you will need to know how many tons are required, based on the dimension (diameter) this for machine capability
here you find tons calculation based on shape and dimensions

there are 2 ways to cut the flat pattern (component unfold), cut on step by step (for example cutting each side by step this is progressive press or a turret punch process)
another way its have the tool with dimensions of flat pattern and with it with one punch (sequnce will be first punch holes and then the component cut) this its called blanking cut
for bending proces could be so easy use a press break machine you should be verify bend allowance, take on mind tooling will be used to make bends verify tools available to make bends
on the drawing, i dont see a internal radius
here it good to use:
