Now your link is working, so welcome to the forum!
You would make it easier for us if you posted pictures here in the forum, and just one fly per thread. The threads should be searchable by visitors.
At the moment it takes a lot of time to load the big files.
No. 7560 seems to be a Tachinid, my guess is Solieria spec.
No. 6226 also belongs to Tachinidae.
No. 6021 is probably a Syrphidae male.
To get a safe identification, pics of better quality are needed, showing the fly at a close distance and from different angles.
