My perspective on when each Visions episode occurs:

1. The Duel obviously takes place sometime before The Phantom Menace as it looks more medieval.

2. Tatooine Rhapsody takes place either during A New Hope and The Empire Strikes Back or sometime after Revenge of the Sith as characters such as Jabba the Hutt appear.

3. The Twins takes place after The Rise of Skywalker as Karre uses an X-Wing: if this is true, the Resistance has likely sold any remaining X-Wings leftover from the Battle of Exegol.

4. The Village Bride takes place during the original trilogy as F's master is seen brutally murdered presumably during Order 66. Reprogrammed battle droids also appear but there are very few as most of the other battle droids were likely melted down after Revenge of the Sith.

5. The Ninth Jedi possibly takes place after The Rise of Skywalker as very few Jedi appear as well sabersmiths.

6. T0-B1: N/A

7. The Elder: N/A

8. Lop & Ocho takes place during the original trilogy as Lop and Ocho's planet is under Empire occupation.

9. Akakiri takes place before the prequel trilogy as force dyads are explored: In The Rise of Skywalker, Palpatine notes that this has been "unseen for generations"

These are just theories and might not actually be correct.
