The oval-piston Honda GP bike was built because Honda thought that a 500cc
V8 four-stroke could compete with a 500cc V3 or V4 two-stroke.  GP rules at
the time restricted engines to four cylinders, though, so Honda simply
siamesed pairs of cylinders together.
They had moderate success with this approach, but I think it was more a
learning experience for them than anything else.

The 5- and 6-cylinder Hondas were earlier bikes from the pre-two-stroke era
in GP racing.  Those were some pretty amazing engines for their time.  I
can't imagine trying to keep one in the powerband, though (which is why some
of those bikes had 7-, 8-, and 9-speed trannies).
