Why "bien" and not "bienes"
I was talking to my friend from Venezuela and I said "Los hijos están bienes" but he told me it should be "Los hijos están bien"... He said that "bien" is a neutral adjective. I'm an advanced speaker and I've never heard of such a thing. But I know that you need to say "están buenos"... So why "están buenos" but not "están bienes"...and by the way, I know know that the word "bienes" means "goods" (as in merchandise).

"Bien" is used as an adverb or a noun. Only as a noun is when it can be used in the plural.
Bueno/a is the adjective.
Any corrections are welcome.
I have never heard of a "neutral adjective" and would like to hear more about it. For me, bien is an adverb modifying the verb están, not an adjective modifying the noun hijos, and hence doesn't change based on whether nearby nouns are singular or plural (or masculine or feminine).
El negocio les va muy bien. / Their business is doing very well. = adverb
Iré, bien en tren, o bien en autocar. / Ill go either by train or by coach. = conjunction
Son de familia bien. / Theyre from a well-to-do family. = adjective
los bienes de un país / the wealth of a country = noun
In English when someone asks "How are you?"
A reply of "I am good" (bien) is incorrect English. It should be "I am well."
You have similar words, but the context of their use makes the meanings different. Jubilado should answer this!
