You can use any combination of CAPI based software in parallel. You just 
need to create the rules for which application shall act on which 
number/service.

That depends on what you want to do. On incoming calls, each application 
gets the information about destination number and bearer-capability 
(service). If you can separate your services with these information, then 
all is fine. Just configure the applications not to act on the others 
numbers/services.
For Fax and Voice on the same number it is not possible, because the 
bearer-capability may be the same. So one application to handle both
is needed.
This can be done with Asterisk/chan-capi. Receiving fax (via CAPI without 
spandsp) is a feature supported chan-capi if the isdn driver supports it.

Outgoing is not a problem, just make sure that one application won't use too 
many channels and block other appliactions...

Having a unique fax extension for each user can be done with 
Asterisk/chan-capi allone and with another fax-software like Hylafax as 
well.
But if you want to forward a call (which was already accepted by Asterisk) 
to another CAPI application, it is not possible. (Well, Eicon has a special 
driver which can do a lot of CAPI extensions, but I did not try this yet).
So if you want to do that, I suggest using just chan-capi for receiving 
faxes and maybe another application for sending faxes.
