Hello @MBraga, you can navigate to Admin → Ticket fields to change the field labels and modify how it’s visible to the customers: 

On the same nore, Multi-lingual ticket fields feature is available from Estate plan with the help of which you’d be able to add translations for ticket fields in different languages and the same would be loaded based on the choosen language/browser language. You can find more details on the same here : https://support.freshdesk.com/en/support/solutions/articles/239337-multilingual-ticket-fields-and-forms

If you have further queries, please post them here and we’d be glad to help. Thanks :)
