Lucifer is not mentioned ever in the Old Testament.
Your verse in Job uses the word מַזָּרוֹת (Mazaroth), which means constellations or perhaps a reference to the Zodiac ones. The verse in context is God asking Job whether he controls the universe, and essentially saying let God worry about how the world is ran.
Your verse in Isaiah says הֵילֵל (Heylel) son of שָׁחַר (Shachar). That first word is a proper name, which probably refers to the planet Venus, the second word there means daybreak. The verse in context is speaking about the eventual destruction of Babylon, and this verse specifically is a metaphor for how the impossible will happen to Babylon, despite their strength and position in world affairs.
