Your plants in the pics look like Philodendron hederaceum to me mate
i think there are 2 different plants in the pics
Seeing your other pics that you posted, looks like A. nidus
Asplenium nidus is a birds nest type fern with new leaves coming out of the middle, this looks more like a microsorum perhaps?
Definitely Dieffenbachia, possibly 'Camouflage'
Anthurium, birds nest type
looks like it needs more light, can you put it outside for one day a week or something
Same thing is happening to me, I am in sub tropical, and for mine at least, it is a water issue or lack there of. If I missed one or two days in...
Sounds like overwatering whats the drainage like?
Might be a small Anthurium colonicum, compare here http://www.aroidpictures.fr/GENERA/ANTHURIUMA-L/anthcolonicum.html
Looks like a light deprived Philodendron
i cant see any "cotton thingie" but maybe see if it is mealy bugs....
What species is it? Do you know
#4 looks like Dracaena surculosa to me......
Last one looks like Haworthia
#5 Agave attenuata
One on the left is Rhoeo
Certainly looks like one to me, do you have any more close up pictures? Interesting plant
Yes they are tough, here in the sub tropics they will grow in no time. Maybe it is just a patience thing if the roots are growing. Is it summer...
Probably ultra rare in cultivation mate
