You may need to talk to the folks who gave you the list of account codes to decipher their true meaning. Unless they are driven by the instructions to the Call Report, class codes are assigned by the individual institutions; i.e. they are not universal among all banks.
As far as the account titles are concerned, if the CD reads "Johnny Doe by Jane and Henry Doe, Custodians" it is not (as you note) a FLUTMA account because it does not reference the statute in the title. Unless it is supported by a written custodial agreement (not likely) then the account title has no particular meaning except in the minds of the people who set it up, including your employee. I suggest you contact the customers and ask them to retitle it using a method recognized by Florida law.
Again, without expressing any opinion on the coding, an account titled "John Smith Revocable Trust" should be supported by a written trust agreement. Otherwise, it is just a bank account and, for the reference to the "trust" to have any meaning, a beneficiary should be named.
