1. The guests talked about a lot of topics on the talk show.

2. The guests talked about a lot of topics in the talk show.

Which one is correct? Do we have to use 'on' here?

3. First speaker, come to the podium, please. And deliver a speach about the topic.
(Is this passage correct? In fornt of a classroom, when there is no raised part made of wood, can we use 'podium' as in the first sentence? What is the name for the part on which a lecturer put his textbook? It is on a floor which doesn't have a flatform.)

You should use "on" in the first example sentences.

4. The comedian plys an improtant role in the TV program.

5. The comedian plys an improtant role on the TV program.
[Thank you for yor help. Do we have to use 'in' or 'on' here?]

Both are correct, but ‘on’ is more widely used.

And be sure to correct the typo — ‘plays.’
4. The comedian plays an important role in the TV program.

5. The comedian plays an important role on the TV program.
Again, both are fine, but I'd use 2.

However, I'd also say "... in the movie" or "... in the play" (not "on").I don't know if there's a specific rule for this, or if it's just habit!
