I have question for when a druid is in wild shape form as a Huge Anaconda, should the damage go by 2D6 as per the "Natural Attacks by Size" table in the rulebook or do we follow the creatures actual attack as per its size (in the beastiery) which indicates an attack at Medium size of 1D4 which would scale up to 1D8 at Huge size. Is this question easy to understand?

The "Natural Attacks by Size" table is merely an average. Creatures may fall above or below those values. As such, use whatever the actual creature says.
There are no huge anacondas in the Bestiary, afaik anyway (the giant anaconda is gargantuan), so RAW, you can not change into one. There is the giant sea snake from Isles of the Shackles that is huge and does 2d8 with its bite.
