First of all, if they're based in Vietnam, then actually enforcing any
copyright claims there (including enforcing a CC-BY-SA license) is
unlikely to happen.

I think so, yes. CC-BY-SA doesn't make any assumptions about other
components (like their program code) that are used in making up the
derived work. It is ok for them to charge money, it is ok for them to
not release their source.
However, the end product must be licensed CC-BY-SA, i.e. anyone's free
to copy it.

Yes.

Yes.

Yes.
However, CC-BY-SA postulates that if things are published they need to
be published CC-BY-SA; if things remain unpublished, then nobody cares.
In your scenario this means that if the person ordering software from
them orders this only for himself and has no interest in sharing it with
others, then there's nothing to force them to give it away!
CC-BY-SA says that they must not forbid their customer to make copies;
but if the customer has no desire to make copies, then there's nothing
to force him.
> There's nothing about having to release the source in the cc-by-sa is there?
No.

They must not, by the terms of CC-BY-SA, deny you the right to copy it.
If they do, they're violating the license and lose the right to use OSM
data. A very interesting legal question now is this: If they hand you
the software and tell you you're not allowed to copy it, they have
violated the license. But does that now give you an automatic right to
copy it nonetheless? After all, you're not only copying the CC-BY-SA
part of the derived product, you're copying something that's partly
their intellectual property. It might well be that you'd be getting in
legal trouble by distributing their software. (Not to mention potential
troubles with the Vietnamese mafia.)
The whole thing would be totally different if they sold their
application separately and offered some kind of paid "conversion
service" for OSM data. In that case, only the resulting converted OSM
data file would be subject to CC-BY-SA, and the application would be
under whatever license they want.
Layman's opinion, of course.
