I just swapped my head on my the motor and I went forth on purchasing new ARP Head studs for the "rebuild". Unfortunately they have been torqued to their specific torque spec and I need to remove the head once more.

- Is it fine to reuse those head studs? Brand new, yet torqued down once.
-After all was done I did start the engine and had it running for about a total time of 1(one) minute. After that it did not run, and I'm in this position now.

You can reuse ARP hardware. Just keep an eye out for stud stretch. As long as you are tightening in sequence and to the torque specs that come in the box (do not tighten to FSM specs, the torque rating is different for ARP) , the head studs should last 5-10 head jobs before showing signs of fatigue.
