Sounds ok to me too, though as mentioned the danio sure would appreciate some company.
Rams share the same type water as Angels and neons.
I don't mind reiterating what has been said - there are many variables to this and calculators like the above should be used as a rough guide only, since it does not take into account variables such as how experienced and diligent the keeper is, how well it is live planted and how much space is taken up by non-living decor, the shape of the tank (actual swimming room) and what equipment is being run. And afer all that personal preference matters - I don't like tanks swarming with livestock and prefer more subtlety to my planted setups.
