How to view site sizes in Modern SharePoint online
The _layouts/storman.aspx page is still accessible from modern sites. In your case links like below should work just fine:
https://mycompany.sharepoint.com/sites/firstnewmodernsite/_layouts/storman.aspx
https://mycompany.sharepoint.com/sites/secondnewmodernsite/_layouts/storman.aspxsecondnewmodernsite/_layouts/storman.aspx
https://mycompany.sharepoint.com/sites/thirdnewmodernsite/_layouts/storman.aspx
If you previously created all your sites as subsite under https://mycompany.sharepoint.com the storman.aspx page would indeed have shown storage metrics for all subsites underneath. Modern sites are all separate site collections so you can only use storman.aspx on a per-site basis.
By default an aggregated view is only available from the SharePoint Admin Center, the new Admin Center which is currently rolling out also shows modern sites here
Hope this helps
