When you ask 'what is this?' in formal Japanese, one would say: これは何ですか.
Colloquially, as I hear it from Japanese friends: 何をこれ. (Am I missing a
particle here?)

So if you are comparing two things, for example: A is cheaper than B. We can
say: A のほうが B より 安い.

Is it ok to say: A のほうが安い. Is it also ok to say: 安いA のほう? (Or does it make no
sense?)

「A のほうが安い」 is ok. It is a comparative statement: _"A is cheaper"_. Alone it
lacks an element you are comparing it to, but you can use it in some context,
just like in English.

「安いA のほう」 makes no sense in the context you asked. The phrase does not have a
verb nor a subject. It is: _pointing to the object A described by an adjective
"cheap"_. It could be a grammatically valid answer to a question "which one
will you take?" (どっちにされますか) "the cheap A" (安いAのほう).

answer
Colloquial japanese tend to skip particles.

これは何ですか。ーー＞これは何？ーーー＞これ、何？ーーー＞何？

But when you speak "spontaneously", the 何 comes first, then you precise what
you are talking about.

何、これ？

* * *

As said in a earlier response, giving context, Aのほうが安い is correct. You have
two (or more) things in front of you, you say A is cheaper.

安いAのほう sound really weird to me but, again as said earlier, giving context it
could mean " let go with the cheaper something"
