If I use Sharepoint as a data source, can I still open sharepoint when I edit/save the powerapps?
More than 10 people will use the powerapps and sharepoint at the same time. So, I need some solution.

Yes, you can be editing and adding or removing items all the time in your SharePoint list while using the app.
The only thing to keep in mind is that, once an app has opened and accessed the list, it will use that list at that moment until a) the app is restarted or b) the datasource is refreshed in the app or c) the data has never been accessed until a certain point.
So, bottom line, yes you can work with both, but the changes in SharePoint are not reflected immediately in the app.
I hope this is helpful for you.
