Get started here Getting started with the Thunderbird main window, then to create a folder, simply right-click your account in the folder pane and choose New Folder in the menu that appears. This will create a top-level or parent folder under your account. To create subfolders, simply right-click the top-level or parent folder and select New Subfolder in the menu that appears. The right-click (context) menu gives you many useful options depending on what (context) you've right-clicked on.

After you have created your folders as needed, you can use filters to automatically organize messages into them as explained here Organize Your Messages by Using Filters, or you could manually move selected messages into their respective folders as explained here https://support.mozilla.org/bm/questions/1027435

Well, I need to have a folder that will contain all my email addresses, because now they are all in the same place https://prnt.sc/ue7cvs BUT I need a part of them to be in the work folder, and the other part in my Home folder.

Create a saved search from File/New/Saved Search..., select 'Match all messages' (unless you wish to apply filters), and add the folders from various accounts you wish to group into the folder. Make a saved search for Work, Home etc.
