The Children Awaiting the Dawn (Flamechurch Cathedral, Temenos/Throne)
Kazan's Plans (Tranquil Grotto, Agnea/Hikari)
Ori's Fate (Fellsun Ruins, Osvald/Partitio)
The First Flame (Tomb of the Wardenbeast, Ochette/Castti)

I don't know if there might be some weird bug with these ones, but I never got the Temenos/Throne one after rekindling the flame, and they were both in the party of course.

Also for the Ochette/Castti one, it came up after I got the boss warning about "you feel a presence" and I chose "No" to turn back, so that seems like a bug. It also doesn't really make sense for her to start saying "So that was the First Flame huh" out of the blue.

Alrighty, I figured it all out!

The Journey to Dawn travel banters (Note: Team setup do not matter at all)

In Search of Clues (is available upon regaining control in the final chapter)
The Shadow and the Endless Night (You have to change screens 30 times, either by leaving an area, or fast traveling. Location does not matter at all)
Places of Truth (You have to change screens 20 more times ater getting the last one)

The last four are available after rekindling a Sacred Flame (for 'The First Flame', it happens just before after beating the boss)

The Children Awaiting the Dawn (Flamechurch Cathedral, Temenos/Throne)
Kazan's Plans (Tranquil Grotto, Agnea/Hikari)
Ori's Fate (Fellsun Ruins, Osvald/Partitio)
The First Flame (Tomb of the Wardenbeast, Ochette/Castti)

Also, to add on to what I found on a reddit thing, when doing the Tavern banters, when you get one, you have to change screens 10 times before you can get another Tavern banter.

Hey, I wanted to ask, do you know how to find all the travel banters for the Final Chapter?

I know you get one at the start, and one at the end of each flames, but there's two that I'm having trouble finding

'The Shadow and the Endless Night' and 'Places of Truth'

Any help would be appreciated.

Hi, for Hikari's chapter 4 can you change it to having to bring Agnea and Ochette to the boss fight? I was super confused until I finished his chapter thank you in advance!

Also it would be great to mention that you can check the 3/4 person banters you have already seen by going into Journal > Sidequests > All and then pressing the button prompt for 'travel banter'.
With this your guide should be fully complete :)

You can also add the story names for convenience if you want to.
And the fact that to see the next you want to change location ~10 times. so ideally you exit/enter some area ~5-6 times before returning to tavern with setup you desire.

Also there are a total of 20 3/4 person banters, you posted 11, here are the remaining 9, last 3 are 4 member ones:
1) Throne/Temenos/Hikari
2) Throne/Osvald/Agnea
3) Ochette/Throne/Agnea
4) Castti/Temenos/Hikari
5) Osvald/Partitio/Temenos
6) Ochette/Osvald/Temenos
7) Ochette/Throne/Osvald/Hikari
8) Ochette/Casti/Throne/Agne
9) Osvald/Partitio/Temenos/Hikari

@Hentaika- thank you very much!

Missing one banter in chapter 4 of Osvald.

It's after beating the main boss - requires Castti with you.

Hikari/Temenos/Castti, "Another Self"

Throne/Ochette/Agnea, "Table manners"
