Div rotation adjustment

I have a javascript function which is refreshing 2 div's in a .php page in a timed sequence. Each time each div is refreshed by the script it is calling (alternately) for 2 different external .php pages (4x pages are called in turn within the 2 Div's). I am needing the script adjusted so that each div is refreshing to alternate between 3x .php pages per div (6 external pages total) in the same timed sequence. All functionality of the script is to remain as is. I am only needing the script to add 1 more external .php page per div refresh cycle. Script function is attached with script adjustments noted. The two additional pages that require adding in the refresh sequence of the script are [login to view URL] in one div and [login to view URL] in the other div.
