Hello,
You can use the first license to activate the mentioned site.
The second license is used on these sites – https://prnt.sc/wj2pem
According to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site, localhost but the same project) – https://themeforest.net/licenses/terms/regular It seems that not all these sites are 1 project. In case you are working on different projects you need to purchase more licenses.
Regards
