Is it possible to retrieve information regarding currently visible holograms, such as their position (Cartesian coordinates) or size? Specifically in the case when I'm using apps developed by others, so I can't manage the creation of holograms myself.

Hello, Welcome to Microsoft Q&A,
Are you developing applications for HoloLens? What development tools are you using? If you are using a game engine such as Unity or Unreal, usually you can get the hologram object through collision detection, and then use the method provided by the engine to get the position of the object.
Thank your for your help.
Currently I'm not using Unity or Unreal, I was hoping there would be e.g. a Device Portal REST API type of solution here. But if I used Unity/Unreal, I would not be able to get the positions of holograms created by other apps, right? Say I wanted to find out the position of the start menu, is there any way of getting that?

The HoloLens device portal does not provide an API for such functionality.

Yes, by default you cannot access the position data of holograms across apps, but if you are using Azure Spatial Anchor and both apps use the same Azure account, then you can try to access the data through Azure Spatial Anchor, you can refer to Frequently asked questions - Azure Spatial Anchors | Microsoft Learn.

If you're talking about the start menu on a HoloLens device, as far as I know there's no way to get its location because it's system controlled.
May I ask what is the scenario? Can you share more details about the project?
