When indicated, our Plugins are licensed “per user”. This means that one license must be purchased for each user working on a project using the Plugin.

This is done accordingly to the Epic Content License Agreement, section “Marketplace Content Addendum”, comma 1 “Marketplace Plug-ins”:

Plugins may be offered to you on a per user basis. Such Plugins may only be used by the number of users that you have purchased licenses for. Distribution of Plugins in source format to your employees, affiliates and contractors is permitted so long as use by those employees, affiliates and contractors does not cause you to exceed the number of paid users you have purchased for the Plugin. Any such Distributions will be subject to the terms of Section 4 of the Agreement. Additionally, any Projects you incorporate Plugins into may only be Distributed as Engine Tools under the Unreal Engine Agreement.

and also confirmed by the UE Marketplace KB:

Plugin files can be shared, but licenses will need to be purchased for each user that will be using the plugin.

So, accordingly to the licensing terms above, each user working on an Unreal Engine project using the Plugin must buy a valid license of the Plugin to use it in the Unreal Engine Editor.
