Hello Lizzz!
One line was already translated into Brazilian Portuguese by Lilian.

These are some excerpts from “Exorcism against Satan and the Rebels Angels†approved by Pope Leone 13th and this is an official English translation which I find good:
Ergo draco maledicte
Thus cursed demon
et omnis legio diabolica
and every diabolical legion
Ut Ecclesiam tuam secura tibi facias libertate servire
So that you may make your Church safe to serve you freely,
te rogamus, audi nos.
we ask you, hear us.
Exorcizamus te, omnis immundus spiritus
We exorcise you, every impure spirit
omnis satanica potestas, omnis incursio
every satanic power, every incursion
infernalis adversarii, omnis legio,
of the infernal adversary, every legion
omnis congregatio et secta diabolica.
every congregation and diabolical sect.
