Relays for ignition, VR, choke and adding AFR?

I’m using blue/brown wires, ignition #1 & #2 tied together for switching on a new relay.
Relay feeds new HEI/e core coil conversion, VR and alternator field and choke, also adding AFR.
Should any of these be powered separately with another relay?
Or can one do it all?
Any and all suggestions appreciated.
