Let me know data about long distance bus from guangzhou to Zhangjiajie, Fenghuang, Huaihua , Jishuo. which bus station do they depart?

Direct long-distance buses to Zhangjiajie, two buses are on scheduled at the local Fangcun Bus Station every day at 13:00 and 13:10. It costs CNY230 per person.

I don't find direct buses to other three places. It is suggested to take train to Jishou and Huaihua.

To Fenghuang, you can take a train to Jishou first and then transfer to a bus to reach that town. Or you can take a bus from GZ city to Changsha first, which can be taken at Fangcun Bus Station or Luochongwei Bus Station and the bus fare is CNY200 per person. Then at Changsha West Bus Station, you can take a direct bus to the town.
