It depends.  For ex., ekiga listens on port 5060, and if linphone uses 
the same port the two programs will not function properly.

The devices themselves should not be a problem I think, since they are 
opened only during communication.

The accounts are not a problem either, as soon as they use different 
providers on the three programs.

Indeed, because that device is opened in one program (which uses it), 
and the other one wants to open it too.
