Name the Cosby Kids

Name the five children of Cliff & Clair Huxtable. Regular visitors to the Huxtable residence, like Kenny and Walter "Cockroach" Bradley, don't count. Neither does step-granddaughter Olivia Kendall (Raven-Symone). We're just looking for the first name. But for an added degree of difficulty, you can try to name the actors. You've got 1 minute.
