Identifying these Japanese names

I’ve found an old declassified document showing Japanese vehicles (planes), but no picture is given, does anyone know which planese these are:

Sam = Mitsubishi A7M

Luke = Mitsubishi J4M. But not completed so may be simply based on projected figures.

The armament setup is pretty wild… 6 x 20 mm cannons.

The 6x makes it the A7M3 Reppū. Again its an unfinished design. Such high cannon counts were surprisingly common in late war aircraft
but few made it past the drawing board or were scaled back to a more usual 4x.

The A7M3 has 4x30mm cannons plus 2x20 mm’s.
If been searching through the internet, and apperently the A7M2 had more then one config.
So instead of the 2x20 + 2x13.7 you could have 6x20.

EDIT:

My mistake, there are multiple A7M3 variants.
