Is it possible to install plugin from Marketplace on-prem environment?
I'm interested to Priorties plugin, which is available as part of the Cloud Jira, but I'm not sure how it could be installed on top of Jira Data Center.

Yes, as long as a server has internet access, it can install marketplace apps directly. If it does not have internet access, then you'll need to download the app and manually upload it.

Cloud apps cannot be installed on server/data-centre. Equally, server/dc apps cannot be installed in Cloud. The "plugin" frameworks for them are totally different and incompatible.
Does the "priorities plugin" you mention have a Cloud version in the marketplace?
