One potentially useful contribution to this that I haven't seen mentioned before. I think the OP said there were several planes that went by, obviously being a formation. The standard practice for formations is that lead will maintain the sqawk for the formation and will be the only one with TCAS operating (if so equipped). The other aircraft will likely be sqawking standby and will have TCAS in some sort of reduced mode like TA only. Or at least that was how it went when I last flew for big blue a few years ago.
I had four traffic advisories from ATC: one of them was a formation, converging from the left about 700 ft below. I noticed them two seconds before they passed - way too late to do anything about it if there was a collision hazard. 2nd one- one airplane, about the same heading and same altitude as the formation, also saw him just as he was about to pass. 3rd and 4th- didn't see them at all, even though they were on my 12 o'clock and 1000 ft above at the time advisory was issued, in a few seconds they were "6 o'clock and no factor".

What's interesting is that the planes that I saw were headed northbound, even according to the VFR chart, the direction of flight along all the MTRs
in the area is southbound..
