Everything is correct except for number 5, which has two prepositional phrases, "behind the door: and "for her friend."

Andy Warhol was a successful magazine and ad illustrator who became a leading artist of the 1960s Pop art movements. He was one of the most prolific and popular artists of his time, using both avant-garde and highly commercial sensibilities. He ventured into a wide variety of art forms, including performance art, filmmaking, video installations and writing, and controversially blurred the lines between fine art and mainstream aesthetics. Later in his life, Warhol suffered from chronic issues with his gallbladder. On February 20, 1987, he was admitted to New York Hospital where his gallbladder was successfully removed and he seemed to be recovering. However, days later he suffered complications that resulted in sudden cardiac arrest and he died on February 22, 1987 at the age of 58.
