The upper stage may not be one of the objects in the train. It should have re-entered at around 21:50 UTC on Jun 30.

The planned disposal location was over the Indian Ocean near 38° south, 70° east. SpaceX does not routinely announce Falcon 9 disposals so there is currently no confirmation that it occurred as planned.

For reference, here is the navigation warning.

Very close ahead of it was another bright dot which I could see distinctly as a separate object in binoculars but which merges on this video. The much fainter dots ahead and behind are the deployed spacecraft and bits of deployment mechanism. They are mostly all very faint but there is some glinting going on.
