I have cs4 product, and want buy only adobe pro, illustrator and photoshop, help me please

As far as acquiring news versions goes, the only benefit you will get from owning CS4 is that you can get a Creative Cloud subscription at a special rate for the first year.  https://creative.adobe.com/#plans

Otherwise, since CS4 is not in the upgrade path for CS6 products, you can purchase CS6 applications at full price.
