axis on the center of all cylinder head.

     I can't help you for a 7 or 9 point arrangement, but if you want a 5 point
arrangement (like in the demo image), you can sorta cheat one by using five #5
angle-connectors linked in a ring.  They aren't exactly 108 degrees, but it is
possible to link them together  An odd number in each ring would make the most
sense, since if you fire every second cylinder going in a circle, it will hit
every cylinder in two revolutions.  Six cylinders can be broken down into two
rings of three, but the cylinder arrangement in that demo pic suggests that the
less cylinders you have, the jerkier the engine will run.
