Late to the party here, but I think you all have nailed the plant ID's except for #1 and 2 which we really do need clearer photos of, please.
I might suggest that C may be the foliage of an Amorphophallus, as it doesn't look quite ragged enough for a fishtail palm to me. But there is only one frond sticking out, and another further to the right.
Did our original poster ever come back?
