Mon Mothma's title was still senator, but she had been on the run for two years by the time of R1 for openly declaring the Alliance to Restore the Republic. Bail Organa may or may not have been a senator in R1, as Leia was suppose to have taken his position by then. Several other senators were likely supporting the Rebellion. Some openly. Some quietly. But Mon Mothma? Traitor to the Empire is likely her other title.
As for Yularen. It depends greatly on just how he sees things. Remember that to most of the Galaxy, Palpatine is the legitimate ruler, and it was the Jedi who turned out to be traitors to the Republic. Palpatine reorganizing the Republic and Separatist worlds into the Empire was cheered in the Senate.
