You will both have access to the SEN lounges. At this time there is no way to buy access to the First Lounges (I believe this was only possible for a few days last year, otherwise they are exclusive to F/HON passengers).

HON's can only guest one person (non-family) to the F lounges, so I wouldn't count on it... not to mention they would have to be flying on the same flight.
