One way to do it is to change the stencil of the note head to incorporate the accidental, and then add the box to this.. (Unfortunately, adding the box to a note which really has an accidental will displace it. I don't know how to accommodate this -- so the "F#" in the box in the example I've attached is really an F# and not an F.)
I believe that if you use 2.14.2, the horizontal spacing won't be adjusted if you change the box size. I'm using a recent development version and accommodation is made.
The last example you show could be approached in a similar way, by adding a clef stencil to the note head stencil, along with the accidental as I've done.
I've typeset the boxed note as a grace note from which I've removed the stem.
You can change the size of the box by changing the number in the override of NoteHead #'stencil.
I hope you find this helpful (at least for single notes in boxes)!
