If I'm not mistaken, they are taken from the Quran itself.
I'm not Arabic trained and can't understand without translation.
Bismillahi

Roheem are names of Allah. Qul huwalLahu
Ahad, Allahu
Samad, again His Names. Qul..
robbinnaas,
maalikinnaas, are few examples. There are 90 over others I'm sure strewn all over the Quran, especially at the ends of suras.
