Answer:
In beginning of "The Schuyler Sisters," Aaron Burr tell about "there's nothing rich folks love more than going downtown and slummin' it with the poor." That's when the three Schuyler sisters are being shown walking downtown when Peggy says warnings like "daddy said to be home by sundown" and "Daddy said not to go downtown." This shows that Peggy usually sticks to the rules. Eliza and Angelica push off the warnings and continue their walk while Peggy reluctantly follows.
The song continues by showing the girls' reactions to the war. Angelica sings "But–look around, look around, the revolution's happening in New York!" This shows that Angelica is not afraid. Peggy says, "It's bad enough daddy wants to go to war," and "It's bad enough there'll be violence on our shore." This portrays her as the 'innocent one.' Eliza says, "People shouting in the square." This portrays her as the 'observant one.' And Angelica focuses on, "New ideas in the air." This portrays her as the 'intelligent one.'
Soon after, Burr comes back and tries to flirt with Angelica. This reveals Burr to be the 'flirty' or 'humorous' one. She rejects by saying, "I've been reading Common Sense by Thomas Paine. So men say that I'm intense or I'm insane. You want a revolution? I want a revelation." Angelica, now accompanied by her sisters, sing, "'We hold these truths to be self-evident. That all men are created equal' And when I meet Thomas Jefferson, I'm 'a compel him to include women in the sequel!" This shows that all three sisters believe in women's rights, but Angelica is one that is more open about it, as she is the one who is focused on.
(I absolutely love Hamilton, by the way!)
