In answer to your questions:
1. Currently there is no option to charge users to submit a resume to the resume page, or when applying for a job. Basically, no charges relating to job seekers is built into the theme and would require customization on your part.
2. This is also not built into the theme, however you can find this functionality available in the
FXTender pro plugin
3. The theme can be translated into any language, however it is not multi language capable in terms of allowing users to select from various languages. Whilst there are WordPress plugins for this such as mentioned
here, it's not currently compatible with JobRoller out of the box. Thanks.
