HTS is an *extension* of HTK, so it has a number of new features not described in the HTKBook.

Yes.

Yes.

The format of .inf files for hts_engine is almost equal to that of HTK.

For example, in HTK format we can save mcep and lf0 trees in one .inf file by constructing all trees in one HHEd execution.
But we need to split them into two .inf files (one for mcep and another for lf0 trees) because hts_engine requires split tree files.
CT command just splits loaded trees into .inf file for stream 1 (mcep) and .inf file for streams 2 to 4 (lf0).
