Can and if so, will, Orion use Soyuz docking port on ISS?

Subject says it all.

And if the answer to the first part is no, why?

No.

Orion will use LIDS, a lightweight adapter originally designed for X-38.

The US has never used the Soyuz docking mechanism for anything. The
shuttle uses APAS, another Russian docking mechanism, to dock to ISS.

Purchasing Russian docking mechanisms after the end of 2011 would
require NASA to obtain an INKSNA waiver from Congress. So NASA has
standardized the Constellation program on the LIDS mechanism, which is
US-designed and built.

I'll start it off. One reason I can think of may be that assuming
Soyuz continues to be used as the 'lifeboat' it's docking port
would not be free for Orion to use. Orion would have to use what
the Shuttle uses. -OR- Orion would have to occupy the port used by
a Progress.

How many docking ports are on the ISS? And what are their configurations?

So I'm left confused, sorry. Is LIDS compatible with APAS? If not, will a
new docking port have to be added to accommodate Orion?

IIRC An adapter will be launched that will attach to one of the PMA's

Orion will use the shuttle ports. They will either be fitted with an
APAS To LIDS Adapter System (ATLAS) or the PMAs will be replaced
completely with a CBM-LIDS Adapter System (CLAS). There is absolutely no
need for Orion to use the Soyuz system.

2 APAS on PMA-2 and PMA-3 (shuttle)
1 hybrid probe & drogue on Zvezda (MRM-2)
3 standard probe & drogue on Zarya, Pirs, and Zvezda (Soyuz, Progress, ATV)

That is one possibility, and the one that is currently the baseline:
APAS To LIDS Adapter System (ATLAS).

The other possibility is replacing the PMAs altogether with a CBM-LIDS
Adapter System (CLAS).

Will HTV be berthed on a PMA or directly on a CBM?

The latter.

Many years ago, the Apollo-Soyuz Test Project demonstrated an
"androgynous docking adaptor." Was that a dead end, or did it evolve
into one of the adaptors now in use?

That's the APAS mentioned above.
