According to this site the name 'Jibraan' means reward!
Although the spellings different i think the name is the same

Peace
I really dunno what linguistic basis would get the site to make 'Jibraan' to mean reward
Jibraan
جبران
from the root
Jabara
جبر
which means to fix ,support, strengthen
so Jibraan would mean the same as the name
مصلح
which means supporter,fixer .....
