Those books are mostly for the General Knowledge portion of the exam which is a CLOSED BOOK EXAM. So, NO, you are not allowed to use them. You can study anything though most of the needed info is in the WIT book. But none of them are allowed open during the exam.
The only open book is your chosen code book during the Part 'C' : Open Codebook Exam. Then you can use your D1.1, API 1104, or whatever.
The Part 'B': Bogus Book, or, more properly, the Book of Specifications, exam has it's own book that is also an open book as far as that goes. But there are no other books allowed besides it.
Highlighting is not a problem with most testing especially for AWS CWI exam. They encourage it. But, only for the open codebook exam.
