Cast order - clarification?

Hi.

I have one series that mainly features interviews from various actors, musicians and celebrities. It's from the late 1990s, so press tours and interviews were a common practice back then. All TV interviews are conducted for the series, so no archive material and such.

Anyway, only the two main hosts, and two guest hosts (if any), are credited in the end credits, others are (usually) credited with captions in the course of the episode (e.g. when Morgan Freeman is being interviewed, the caption "Morgan Freeman" appears on the screen).

Questions:

1) From the guide:

• "For documentaries or talk shows where the people appearing on camera are generally not in a separate cast list, their first onscreen appearance where they are identified either by a caption or spoken name is used to determine the order. Any narrator/host listed in opening or closing credits would be treated as the first cast member, and would precede people identified only within the documentary."

In my case there's an episode where the "guest hosts" are introduced first (via spoken name - and later via captions), and the "main hosts" are credited in the end credits. The "guest hosts" are also credited in the end credits, but only after the main hosts.

Am I correct in my understanding that the "main hosts" still receive the credit order 1 & 2, and the "guest hosts" credit order 3 & 4? Even, when the "guest hosts" are basically introduced first in the episode?

2) In one episode, there are interviews with the selected members of the band Slayer - but (for some reason of another) they're not identified either by a caption or spoken name. At some point the caption "Slayer" appears, but not the actual names of the band members.

So, are they added:
- In the order number they appear in the episode, with the (e.g.) name: "Araya, Tom" - - - (as Slayer)
OR
- No order number, with the (e.g.) name: "Araya, Tom" - - - (uncredited)

3) During the episode, two persons from another pop group gives a short promo of the episode (like: "Stay tuned for music from Slayer, coming later in this episode.."). The persons are not identified either by a caption or spoken name but, like with Slayer, their group is credited on the screen. The first name of the other person is mentioned, though (no captions).

So, are they added:
- In the order number they appear in the episode, with the (e.g.) name: "Doe, John" - - - (as The Band)
OR
- No order number, with the (e.g.) name: "Doe, John" - - - (uncredited)
OR (the person whose first name is mentioned during the episode)
- In the order number she appears in the episode, with the (e.g.) name: "Doe, Jane" - - - (as Jane)

Thank you.
