Is the word números the same in Brazilian and European Portuguese?

Yes

The word "números" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels (like the "o" in números) tend to be more closed or reduced, and the final "s" is typically pronounced as a "sh" sound (palatalization), whereas in many Brazilian dialects, the "s" is more sibilant or varies by region.

3. Os números estão aumentando muito. (The numbers are increasing a lot.)
4. Você viu os números do placar? (Did you see the numbers on the scoreboard?)
5. Verifique os números na tela. (Check the numbers on the screen.)
