I can't help with all these plants, but there are a few I have some
opinions about:
(1) Wildenowii Fern (selaginella).  Selaginella is in the Division
Lycophyta, which also includes club mosses, Lycopodiaceae, and Isoetes.  As
far as I know, there are no aquatic Selaginellaceae or Lycopodiaceae  I
would bet this is not aquatic.  I have also seen club mosses being sold as
aquatic plants, but they most definitely are not. Don't buy it.

(2) The Crypt:  Did it have mostly green leaves with irregular red streaks?
If so, I have it too, and I am not sure if it is a variety of C. wendtii,
or some other species in the C. beckettii group.

(3) Hair grass is genus Eleocharis.  There are a lot of species suitable
for aquaria.  It makes an even finer leaved "lawn" than pigmey chain
swords. It does not do well in dim light.
