Welcome to WebmasterWorld Barsha.
how valid is that?
Editing by hand doesn't invalidate anything. I often edit feeds in a text editor. To make sure there are no problems just run the feed through a FEED validator [feedvalidator.org].
how to fast update the feed?
As soon as the feed is uploaded to the server it's updated. The services that read your feed are another matter. You need to ping [google.com] the various services to tell them to get your new feed. Otherwise they will default to their own schedules.
