1) Subs are typically quite a bit stronger than cubes (cubensis). I've never done them.
2. Amazon is a cube.
3. Not a mushroom, as has already been said.
4. Another cube.
Golden Teachers are another cube. Any of the mushrooms you listed would be good for tripping, but if you do #1, make sure you back the dose down accordingly. I can't remember the rough conversion for dosing Subs, but you'd want to look that up online beforehand if you get those.
