We believe there is not reason to connect them separately and we are trying to save some spots for motors and additional electrical loads such as proxes. If the proxes can be wired together under the same circuit then we won't mind about the relays.
And related to the proxes? Are they allowed to be connected in the same circuit under the same fuse?

I assume by "proxes" you mean the photosensors? Or is this another part I'm not recognizing?
Those can be connected to the same circuit because they individually draw very little power, and a 20A circuit breaker is very excessive. They also have integrated short circuit protection.
Spike relays on the other hand could be potentially switching up to 20A per relay, and multiple ones could easily overload a single 20A breaker. I understand your particular application doesn't pose this risk, but the rules must be able to apply broadly to be effective. As such, to the best of my understanding, you can only have one Spike per breaker.
You may have better luck considering a custom circuit board option for your LEDs, a little bit of LEDs, resistors and standard transistors from RadioShack and you could be in business with a single power soure and a couple of Digital Outputs. If you need help with that idea, let us know!
