[Can you have more then one mega evolved pokemon on your team?]

I have a gardevoir and an Ampharos but i dont know if i can mega evolve both at the same time. anyone know if i can or cant?

i dont have the mega stones yet.

[Im getting 2-4 fps when I'm exploring. anyone know how to fix this?]

Its only lagging when im exploring. if its anything else its completely fine.
