In Petals, an orchestration is mandatorily a service.
It is a way of implementing a service contract, by invoking other services.

It depends...
What "each one" refers to? The async BPEL processes?
In a general matter, all the services to orchestrate must be "visible"
inside Petals. If these services are available as web services, then, you
will have to create one service-unit (provider mode) for every of them.

No, only the ones you want to invoke from outside the ESB.

Which jbi.xml? If you use both the SOAP and BPEL components, then none of
your jbi.xml will contain both a provides and a consumes section. One
section means one artifact.

You can follow the  tutorials of the studio
<https://doc.petalslink.com/display/petalsstudio13/Tutorials>   to create
the projects. Here, you want to import web services in Petals, create BPEL
processes and maybe expose one of them as a web service.
