Wale is calling this woman a “10” (dime) and telling her that the other “broads” are “peace up.”

D-WHY can go to places that the rest of us can’t get to. Like VIPs and private lounges.

“Thirsty” means wanting something really badly or desperately. D-WHY desperately wants to be at the top of the game, but it also leads into the next line of wanting a macchiato which would mean he is also physically thirsty.

D is referring to the Broadway in New York City, which is famous for its musical performances that are held there. He is also using this line to preface the fact that he’s getting ready to sing the last part of the song.
