How I can make Bind9 to stop answering specific types of queries, let say NULL, WKS or TXT?

Thanks in advance.

Unfortunately, no. The "blackhole" facilities of BIND 9 are extremely limited (a fact that's been exploited for a variety of back-scatter attacks). If you're running Linux you can configure IP Tables to drop packets with those types of requests. A vaguely similar Q&A has some good information in it.
