What is "ha'Buzi"?
Ibn Ezra: He is from Avraham's brother Nachor - "v'Es Buz Achiv." Perhaps he was from the mother's family, like Ya'ir ben Menasheh was from Bnei Yehudah (Divrei ha'Yamim I, 2:22).
What is "Mishpachas Ram"?
Rashi: It is Avraham. "Ha'Adam ha'Gadol ba'Anakim" is Avraham (Bereishis Rabah 14:6).
Ibn Ezra: Ram was the father of Aminadav (Rus 4:19), a Jew.
Why was he angry at Iyov?
Ibn Ezra (here and 42:17): Iyov considered himself more virtuous than Hashem, and condemned Hashem amidst his great pain - "Hodi'eni Al Mah Teriveni"(10:2).
Malbim: He was angry at both sides. He was angry at Iyov - even though Iyov knew that he was a Tzadik, and did not know the reason for his afflictions, he should not have attributed injustice to Hashem. His intellect, which knows that Hashem acts properly, should have overridden his sense that he is virtuous.
What is "me'Elokim"?
Rashi: [He considered himself more virtuous] than Hashem.
