Commandment no 5 The prohibition against theft !!!!
A gentile is liable for violating the prohibition against theft whether he stole from another gentile or from a jew.
This applies to one who forcefully robs a individual or steals money;a kidnapper;
an employer who withholds his worker:s wages and the like a worker who eats from his employer;s produce when he is not working.in all such he is liable and is considered as a robber.with regard to jews the law is different.
Similarly a gentile is liable for stealing an object worth less than a prutah
.thus if one gentile stole an object worth less than a prutah and another gentile stole it from him; they are both executed because of it.
להלן ראה מה שכתב הרמב"ם בסוף פרק ח הלכה 11
בן נח חייב על הגזל-בין שגזל עכו"ם בין שגזל ישראל
אפילו פועל שאכל שלא בשעת מלאכה-על הכול הוא חייב והרי בלל גזלן:מה שאין כן בישראל.
וכן חייב על פחות משווה פרוטה.ובן נח שגזל פחות משווה פרוטה,ובא אחר וגזלה ממנו –
שניהן נהרגין עליה.

Anyone who accepts upon himself the fulfillment of these seven mitzvot and precise in their observance is considered one of the pious among the gentiles and will merit a share in the world to come.
This applies only when he accepts them and fulfills them because the holy one
blessed be he;commanded them in the torah and informed us through moses our teacher;that noah;s descendants had been commanded to fulfill them previously.
However if he fulfills them out of intellectual conviction he is not a resident alien;nor of the pious among the gentiles;nor of their wise men
