I forgot to ask the question here.
I though that only Dolichopodidae are predators in this size range. However, none of these flies looks like a Dolichopodidae. What family do these flies belong to?

They are Muscidae or Anthomyiidae. There are predators in these families as well. Maybe Kahis can fill you in on those.

Me? But but but ... I'm no muscid man:o:|
Having said the truth, I am now free to speculate :) My vote goes to
Coenosia, or at least tribe Coenosiini of Muscidae. This genus holds the smallest muscids and some species are extremely common on meadows and among grass on shores. Little is known about the lifestyle of adults, but at least some species are predatory.
Coenosia females are often much darker than males and it is sometimes difficult to associate males and females of the same species.
I think the small yellow fly in the 3rd pic is a chloropid.
