I assume you're asking about the branch of government, Executive, Legislative, or Judicial.
The Judicial is the supreme court, with nine justices (the words judicial and justice come from the same root, see).
The nine US Supreme Court justices belong to the Judicial Branch of government; however, it would be inaccurate to say this branch is "made up of" the nine justices, as that implies the Supreme Court is the only entity within the Judicial branch. The entire federal court system is also part of the Judicial branch.

The judicial branch consists of judges and courts such as district courts (thus district judges), appeals court and judges and the highest court in the USA, the Supreme Court and the 9 justices.
no judges are in the judicial branch
the legislative branch confirms judges
In the United States, there are currently 9 Supreme Court Judges, 179 Appellate Court Judges, and 678 District Court judges, plus a number of judges assigned to special purpose courts. In addition, there is a large collection of special-purpose sheriffs, bailiffs, clerks, and other associated personnel which support the judges. A good guess at the total number of people employed by the Federal Judicial branch would be in the 10-20,000 range.
