Since this is not my area of expertise, I searched Google under the key words "cricket umpire signals" to get these possible sources:
There seem to be more than eight.
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
