No.
RES are usually too aggressive for other species, and generally do best on their own.
Anytime you add two turtles together you have to be prepared for the chance that they will need to be separated for life. Unless you have the means and space for two adult turtle set ups I wouldn't recommend adding turtles.
2 RES: Leo (f) and Ezra (m)
1 Russian Tortoise: Godzilla (m)
