Hi Gustavo, they are correct and this way it´s easier to say.

No. These sentences are perfextly correct! Congratulations! :)

They are very good and grammaticaly correct, but they are closer to written language, mainly if we talk about Brazilian Portuguese. I couldn't say there is 'an easier way to convey' but there is an oral way to say these.
