Yes, all correct #3 is actually nigra 'Megurochiku' but it is a form of nigra Henon so you can not tell from the shoot. I think all but #1 are correctly identified and it will be easy I think, so this will be 20 bamboo that forum member have identified from only the shoot photos - no other information. But the juvenile bamboos you can not do this with because they do not show true form yet and usually when people ask for ID help they are juvenile plants!
