2:42 - Ezra (as Kanan pulls him through the air using the Force): "What the?" In Attack of the Clones, an alien on Coruscant makes this same exclamation as he sees Obi-Wan flying through traffic while hanging from a droid [15:08]; Han Solo says it in A New Hope after emerging from hyperspace into a meteor shower [1:03:15]; and in Return of the Jedi, a scout trooper says this after being hit by Wicket [1:05:38].
7:29 - Hera (to the rest of the rebels): "Good luck." In The Empire Strikes Back, an unidentified Rebel pilot wishes Luke good luck [36:02] and Luke wishes Lando good luck [2:00:09], and in Return of the Jedi, Han and Lando wish each other good luck [Han to Lando at 50:33 and Lando to Han at 52:21].
8:22 - Kanan (to Ezra, after he loudly runs into the door): "You're lucky every stormtrooper in the prison doesn't know we're here." Luke makes a similar complaint to Han Solo in A New Hope: "You know, between his [Chewbacca's] howling and your blasting everything in sight, it's a wonder the whole station doesn't know we're here" [1:08:56].
13:30 - Ezra (on his comlink): "Spector Three, come in; it's a trap!" Admiral Ackbar says, "It's a trap!" in Return of the Jedi [1:35:03], and Leia says it twice in The Empire Strikes Back [1:39:50].
15:32 - Stormtrooper (to other stormtroopers): "Hold your fire!" Obi-Wan also says this to Anakin when he tries to shoot the buzz droids off Obi-Wan's starfighter in Revenge of the Sith: "Hold your fire! You're not helping here!" [6:03]
20:23 - Kanan (to Ezra): "What're you talkin' about?" This line appears three times in A New Hope: twice, C-3PO asks R2-D2, "What are you talking about?" [6:51 and 9:47], and later, in response to Luke's urge to rescue Leia, Han Solo asks, "What are you talkin' about?" [1:11:03]. In Attack of the Clones, Anakin also asks Padmé, "What are you talking about?" [1:43:07].
