Theres like 7 styles. And Dooku was the most learned student at the Temple (even in canon). So Dont know why youve decided he doesnt know all of them.
In the ROTS novelisation hes aware of the strengths and weaknesses of Ataro, Soresu and Djem So. In the old EU he knew a fair bit about Vapaad as well. He obviously knows his own form. So thats already 5/7.
The GI has learned to use/counter ALL the forms of combat:

So it's logical to assume that Dooku would have as well.
