The documentation says:
  typedef std::pair<Cell_handle, int> Facet;

Then, it means that you have to look at the documentation of std::pair, to 
get 
your answers.

The constructor Facet(Cell_handle, int) is the constructor 
std::pair<T1,T2>(T1,T2).

You can also use std::make_pair.

No. You need to write:
  Facet f = Facet(cell, i);
or:
  Facet f(cell,i);
(the latter construction triggers a bug in Microsoft VC++ compiler).
