Power Apps Add Picture Control And Save To SharePoint Library

Question

I have created a demo to capture a photo and upload that into the SharePoint online document library.

I have used Picture Control of PowerApps and the SharePoint document library.

I have taken reference from the below link,

I have a few questions regarding uploading captured photos in the SharePoint document library.

1. Can I upload multiple pictures using PowerApps Picture Control under the SharePoint document library?
2. Can I create a document set in the SharePoint document library using only PowerApps (without using Power Automate)?
3. Can I create a folder and upload multiple images under that folder while the user captures multiple pictures and upload them to the SharePoint document library?
4. Is it possible if an internet connection is not available then save images locally and upload that images in the SharePoint document library while connecting to the internet?

Thanks
