Is fluffy made by fiber cotton, like this one en.wikipedia.org/wiki/Cotton ? I suspect that because fiber cotton is unique in my country; hence, I need to be assured before buying. How much (weight/thickness) should I use it per one 2' by 4' panel? and is it filled in corners like picture below? Attachments:

I believe cotton will work as an acoustic absorbing material. You should try to get acoustic performance specs from the manufacturer. If you can't, search for generic data on the web. In the wiki article, there are specs for critical temperatures indicating that cotton is flammable so that should be a concern. Try to find fiberglass. One member here suggested polyester so you may want to consider that too.
Cheers,
Rock

Yes, if you mean fluffy (low density) fiberglass can go in the same place as the cotton.
Just so you understand, filling the space with "fluffy" improves on the rigid fiberglass across the corner but it's better to cover more corners with only the rigid than less corners filled with fluffy.
To put it another way, make sure you can invest in treating all or as many of your 12 corners (if your room is a simple rectangle) as possible before worrying about filling them. However, if you can afford to fill them too, so much the better!
Cheers,
Rock

It is directly harvested from a tree called by same name. It can absorb water up to 65% of its mass. |

If your country is arid, I suppose something that absorbs water is OK, but where I live, it gets humid especially in the summer and mold can be a problem. You don't have to convince me, it's your decision; but for acoustic applications, if it was for my use, I would verify the acoustic properties, as I mentioned earlier.
Cheers,
Rock
