Microsorum pteropus 'Narrow-java fern
Nymphoides sp. "Taiwan" -rosette
Ludwigia repens 'Rubin' -stem plant
Microsorum pteropus 'WindelÝv'-java fern
Pogostemon helferi -stem plant-send out side shoots to propagate from
Taxiphyllum barbieri-java moss
Vesicularia ferriei 'Weeping moss'
Vesicularia dubyana 'Christmas'
Hygrophila difformis-stem plant-wisteria
Echinodorus tenellus-rosette-pygmy chain sword
For a soil based natural planted tank-you really need to start out with more stem plants. The plant on your list are all great plants, however, you have a lot of moss and fern-while they are awesome-too many IMO-I would pick 1 or 2 each of the moss and fern that you like best and start with those.
Crypt is a nice rosette and work great in soil based NPT
The Vallisneria nana is also a nice rosette and will give you some height, contrast. The corkscrew Val might be a better choice for a 5gal IMO.
The Echinodorus tenellus-another nice rosette that will do well in a NPT
The 3 of the 4 stem plants are all nice and work well in a NPT, however, the Pogostemon helferi is one I have never personally kept/grown and can't say if it will do well.
Other good stem plants that I have had great success with in my soil based NPT's.....Naja grass, Cabomba caroliniana, Hygrophila corymbossa, Hygrophila siamensis, Rotala indica/rotundifolia, Lugwigia natans.
I would also recommend floating plants-like water lettuce or frogbit or duckweed.
