There are several conversation between them, and most of them are enough for a pass.
There's a conversation between Yumi and Atsuko, but it's mostly about her missing father. The only part in which they talk about themselves is one-sided - Atsuko starts, but Yumi quickly changes the subject to Atsuko's affair with her father. While this one doesn't pass, later the two talk again, this time about Tomie.
Yumi and Yoko talk about themselves and several other topics, including work, their well-being and other day-to-day topics. Being daughter and mother, there's a lot of dialog between the two that is enough for a pass.
Yoko and Atsuko also talk, and even though they also mention the affair, it is mostly about Yumi.
At a certain point Tomie talks to another Tomie about Yumi. Even though they are the same actress, they are different beings. Or at least different iterations of the same being. So I believe it counts.
Finally, Tomie and Yumi have a long conversation in the climax. Sure, her father and Tomihito are mentioned repeatedly, but there's enough talk regarding other topics to count towards the pass.
