Hello and welcome to Android Central Andre Martire!

I am sorry to say that you are screwed!

AT&T's own Lollipop firmware does not allow downgrading or rooting whatsoever. See #1.6 of 41 Galaxy S5 models - Dummies Guide

Also, AT&T, unlike Samsung, do not release their firmware for updating or flashing via Odin. See posts #6 & #7 of [Bricked?] ATT S5 SM-G900A attempted downgrade from 5.1.1, now stuck at samsung splash screen

"the only solution so far seems to be to throw yourself on AT&T's mercy and see if they will flash the firmware for you... possibly at a cost as it will probably not be covered by warranty."

our! So do not even go back to stock rom? ?
Otherwise, you could give me a hint of how I put it entirely in Portuguese in Brazil?

Unless you can find a stock AT&T flashable firmware for Android 5.0 or 5.1.1 you will not get your phone working again. The G900A, unlike the G900M or G900F, only has a very limited number of languages available for it and you cannot root your phone to install a multi language custom ROM.

I am currently with version 5.0, you must know where the meeting 5.1.1?

The AT&T firmware for the G900A is released by AT&T and not Samsung. You will need to be registered on the AT&T network to receive their Over The Air Update to Android 5.1.1.

Reviving this topic, I wonder if there is any way I can get back my s5 to version 4.4.2?

No

is there any way I can leave it in Portuguese language?

Does the AT&T model, G900A, even come with Portuguese language pack built in?

If so, go to Settings > Language and input and select Portuguese.

in version 4.4.2, I have access to the Portuguese language. Atuamente in version 5.0, I do not have the language to Portuguese.
You have a solution for this? (Apk something like that)

SM-G900A is an American phone. If you can sell it and buy a SM-G900F, you will have many many more options.
