The word "lights" [SIZE=-1]in v 14 is "ma'owr[/SIZE]" which means light, luminary
The description that follows makes it obvious it is speaking of the plantets and what we call stars in the sky.
Verse 16 has a broader meaning which is demonstrated in your definition as well: "figuratively a prince"
Num 24:7 uses this word figuratively, Judges 5:20, Job 38:7, Dan 8:10,
"star" ([SIZE=-1]kowkab) [/SIZE]is used when speaking of the Messiah, Jacob's brothers, the angels and other angelic beings, God's omniscience (fig.)
And sometimes it is used referring to what we call stars.
Just like the heavens can refer to either the sky or paradise with God.
Like I said before, I can't prove that particular word at the end of v 16 is speaking of angelic beings - It is just my opinion.
