Is it allowed to run both 110v wire (either THHN or Romex) and low
voltage alarm wire (e.g., 4 conductor 22 gauge) in the same 1/2" rigid
metal conduit?

I probably will have one 2-conductor #14 Romex wire for overhead
garage light plus a couple of alarm cables for the window, door, and
heat sensors.

Thanks

According to the NEC, you can only have signalling voltage and line
voltage in the same enclosure if it's a listed assembly. (Furnace,
air conditioner, etc.) Short answer, no!
