Beeline's set up as the latest chronologically since the villains all know each other.
Super Who could take place after the Sweet Justice 4 parter.
Hate Triangle's seems like an early episode.
She might be giant shows Karen getting her new suit, suggesting it should be early, but Livewire and Giganta already know each other. This is also an intro episode for Giganta so it probably takes place after Shock it to me.
Meet the Cheetah should take place before Shock it to me, as Barbie's already introduced.
Burrito Bucket takes place when Babs has Barry's phone number, or at least Flash's, so we're still due a flash episode.
Fight at the museum is probably an early one too to introduce catwoman.
Chronologically I'd say Sweet justice intro, then Super Who/Hate Triangle/Fight at the museum, then Meet the Cheetah, then Shock it to me, then She might be giant, then Beeline.
