I cant pick a Design !!

well I wouldn't but it has nothing to do with port noise, it's so the port loads the chamber and not the second port.

the one with thte middle ports will act like a series tuned 6th order instead of a parallel

I agree with this also, in theory.

The rear port right in front of the external one will cause over/under pressure disturbance in the front port (degree depending on power level and tuning).

Of those choices, I would go with the port to one side for the reasons stated above.

...but if it were me, I would have two ports, half the size, on either side. But that is just my OCD kicking in.
