I would like to know which plugins are these
What do you mean what plugins? Like what plugins control buyers’ badges?

Envato and the marketplaces are not built using WordPress or Plugins (I believe they use Ruby on Rails) so most of what you see will be bespoke coding.
If you have a site using some other form of commerce then it may be possible to custom create this feature
