>>9700331: Yes
2: If raw and unsalted/cooked/roasted, yes.
3: Only if they are still in their shell. Some companies may kiln dry them though in order to loosen them from the shell to all easier shelling. This occurs naturally anyway, they just speed it up. Kiln dried nuts in the shell are probably not viable. Some tree nuts need scarification and cold stratification to sprout.
3: Yes
4: Certainly
5: Yes
6: Maybe, it depends on the drying method. If they were kiln dried then probably not. I'm testing dried goji berry seeds. (Hopeful!)
