Although all the titles listed above are American plays dealing with AIDS, only the 1993 Angels in America: A Gay Fantasia on National Themes was written by Tony Kushner. It is by far the most famous work of the Kushner’s and includes character doubling, interweaving storylines, and various angels and imaginary friends. 

The play described is The Odd Couple, which follows the tiffs and jokes of Oscar, a notoriously laidback slob, and Felix, an extremely organized neat-freak. The play’s main premise is that the two recently divorced main characters become roommates out of financial necessity but end up forming their own close relationship.

The play in question is A Raisin in the Sun, a work that portrays the experiences of an impoverished black family in mid-century Chicago. It is known for its cast of almost exclusively African-American characters as well as its involvement in a U.S. Supreme Court case about racist housing policies.

The theatrical genre described in the question is vaudeville, a genre that developed in late-nineteenth- and early-twentieth-century America. It has its roots in a range of different disciplines, including stage magic, burlesque, circus sideshows, and musical theater.

The author is Edward Albee, an award-winning American playwright who was born in 1928. The play follows the disintegration of the marriage of an impotent middle-aged couple and is remarkable for its interplay of reality and illusion.

The play described in the question stem is Tom Stoppard’s Rosencrantz and Guildenstern are Dead, which follows the offstage adventures of Hamlet’s two hapless friends. The conceit is that the eponymous characters are confused by the plot of Hamlet, which they aren’t privy to, and this conceit allows Stoppard to pose strong existential questions about human purpose and determinism.

Glengarry Glen Ross was written by David Mamet and won the Pulitzer Prize in 1984. It centers on the machinations of four unscrupulous real estate agents in Chicago who are trying their best to sell the two pieces of real estate in the play’s title. It is known for its exquisite dialogues and attention to language.

These lines are from the 1893 play Mrs. Warren's Profession by George Bernard Shaw. This quote is by Mrs. Warren (a former prostitute and current brothel owner) during a conversation with her daughter, Vivie. Vivie has returned home from college and is finally aware of her mother's occupation, causing much debate throughout the course of the play.

These lines are from George Bernard Shaw’s 1913 play Pygmalion. The play centers on Eliza Doolittle, a seemingly simple Cockney flower girl, who Professor Henry Higgins attempts to transform into a sophisticated and well-spoken lady who can pass as a duchess. The name of the play comes from the Greek mythological character, Pygmalion, a sculptor who falls in love with his sculpture when it comes to life. The passage contains two majors clues as to its source material: it mentions "Eliza" and it discusses manners.

These lines are adapted from of William Congreve's play The Way of the World, first performed in 1700.
