Can you appeal to California Supreme Court, if the Court of Appeals deems you a vexatious litigant? Are there any other remedies?
You could possibly seek review by the California Supreme Court, but quite frankly, I suggest you don't go there.

Mr. Chen has good advice. Any appeal is hard to win, but the baggage of having been held to be a vexatious litigant stacks the deck even more. Unless you have a clear case of the law being applied in error, as opposed to a factual determination, you should quit before you get further behind.
