State boundaries
District courts hear cases on topics assigned to them by Congress, and federal courts hear cases regarding constitutional law and treaties.
District courts are part of the federal court system and handle cases within a specific geographic region, while federal courts refer to all courts established under the U.S. Constitution, including district courts, appellate courts, and the Supreme Court. District courts are the trial courts where most federal cases begin, while federal courts encompass the entire federal judiciary system, including appellate and Supreme Court levels.
A judge is assigned to particular branch (either civil or criminal) of the District Court to which they are assigned. Normally they rotate every so often but at the direction of the Chief Judge of that particular district.
The US Courts of Appeal have jurisdiction over the decisions of the subordinate US District Courts assigned to their responsibility. They hae jurisdiction over any trial or action which may be appealed to them but they are not a trial court.
For US and most state Distict Courts - there is no set number of judges assigned. There is a sufficient number assigned to hear the caseload of that paricular court but since they all hear cases individually and no cases are heard "En Banc" at District Court level the number of judges assigned to that particular court is not germaine.

U.S. District Courts
The number of judges assigned varies as to the size of the circuit it serves.
Local courts and district courts.
Yes and no. There is, necessarily, a high court in every state (e.g., the California Supreme Court). These courts hear appeals from the state trial courts, which are sometimes called "district courts" depending on the state (for example, in Washington state, the county district courts have exclusive jurisdiction over small claims and infractions). Usually, however, the term "district court" is used to mean the United States District Courts. The U.S. District Courts are federal courts (not state courts), and there is one in every state and territory, but that is a measure of jurisdiction only, and the state geographical boundaries are by no means necessary. The U.S. District Courts are the federal trial courts and cases are appealed to the U.S. Circuit Courts (U.S. Courts of Appeals) and the United States Supreme Court.
Federal district courts have jurisdiction over trials. Federal appeals courts have jurisdiction over appeals from the federal district courts.
