I tried touching each mic to see what order they are in, and it looks like there is a problem of mixed tracks. I recorded myself saying the mic number, before touching each mic in order ("mic 1" *touch 1*, "mic 2" *touch 2*, "mic 3" *touch 3*, "mic 4" *touch 4*, "mic 5" *touch 5*).
Here is the recorded audio:
