If that's a high-solids content lacquer that is already on those surface areas, which it most likely is, then your going to need something much stronger than lacquer thinner to get the finish off the surface areas.
I would recommend a heavy paste remover and then using a lacquer thinner to clean things up after the removal of the finish. I just use paper towels folded into quarters in order to do the cleaning with the lacquer thinner after doing the heavy stripping. You may need to apply a stripper twice in order to get all of the finish off.
I do totally agree that the colors look very much like the ones that you will find using Minwax stains before applying a clear-coat of lacquer as well as using adequate ventilation no matter what you do.
With the door faces as well as any drawer fronts that you might need to refinish, my recommendation would be to remove them and take them outside to work on them. Working on them while they are placed in a horizontal position, you will get much more satisfactory results when stripping them and then subsequently staining and applying a finish to them.
Thanks for providing the images! How would you like them to look? What is on them shouldn't be all that hard to strip off following all of the directions and precautions that you will find on the can of stripping solution. Oak is so open-grained, that it's easy to change the color of it. But, it might not be so easy to get an existing color out of it by stripping, because it is so open-grained. A lot of sanding using a palm sander may have to happen.
