He is too fast , is it ok ?

[ZuMako8_Momo]

No. "too" would be «demais» or «demasiadamente»: «Ele é rápido demais.» or «Ele é demasiadamente rápido.».

[Danikalifornia]

He is really fast? Is that an incorrect translation?

[Paulenrique]

That should be accepted!

[ZuMako8_Momo]

Technically, it is incorrect. "really" is akin to "truly," which would be «verdadeiramente», and "very" is «muito», but the two words in English are used very interchangeably in everyday speech. ;D
