Re: 6 flag pole question.
Well . . . if you want to get very technical, there's no way to do it without violating the flag code. Section 7f says:
"When the flags [of States, cities or localities] are flown from adjacent staffs . . . No such flag or pennant may be placed above the flag of the United States or to the United States flag’s right."
For practical purposes, I'd say that height should take precedence over right-to-left. The average observer is more likely to interpret height as an indication of superiority or subordination. The right-to-left precedence is a well-established convention, but is less likely to be a concern to the non-specialist. (However, stand by for the nit-pickers who want to beat you over the head with the flag code!)
There is an apartment complex near my house that has a somewhat similar arrangement at their entrance: Three poles of decreasing height in a line. They normally fly US flags on all three poles. There's nothing really wrong with that, I suppose, but it always looks strange to me.
