If you can speak Japanese call JAL Japan -- otherwise NA is probably better.
Since you are transiting HND this is simpler (than NRT) -- when you check in for JAL in BKK (assuming they will manage the luggage) you will have to show them your reservation on ANA -- so have the itinerary with flight numbers printed out.
You should be able to check in online for ANA -- download the ANA app to your phone -- we use it all the time and it works well enough... If that doesn't work for you they do have transit desks at HND where you could get a boarding pass easily.
