u/dmg04 or u/Cozmo23 are the Seraph Bunkers and legendary Lost Sectors separate activities, or are the Seraph Bunkers just legendary Lost Sectors?

Separate.

While we’re at it, is that ‘Iron Banner Exotic Quest’ or ‘Iron Banner, Exotic Quest’?

It’s hard to tell if those are separate items or 1 item split over two lines

Two different things.
