Hello, Arizvy,
According to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site and/or localhost, but the same project), read more – https://themeforest.net/licenses/terms/regular If you want to use our theme for a few different projects you need to buy a few licenses.
If you have any additional questions or concerns, please do not hesitate to reach out to us. Our support team is always available to assist you.
Kind Regards,
8theme team
