Revolution Slider, Visual Composer and Layer Slider are premium plugins that we have bought extended licenses of them to be able to include those plugins on our theme for free. So you can use those plugins without any problem. Those plugins offers some extra features that are activated only if you purchase a copy a those plugins. Then you get the support for those plugins if you need to support from the author.
We also wrote about this on many pages of our documentation site.
