1. Family Scatopsidae (they are midges, by the way). Not possible to say what species, or even genus, from this picture.
2. I am sure it is Calliphoridae. But if it is not Lucillia, then maybe [/i]Bellardia[/i]. There must be several others that are greenish, maybe even more in the East Palaearctic than in the West. ;)
3. This must be Tephritidae. In virtually all 'northern' Pyrgotidae the ocelli are absent and you can see ocelli shining in this picture. Otherwise, wing venation is almost always good to identify Tephritidae, with the subcosta clearly bent towards the costa (often at a [almost] straight angle) and clearly weakened after the bend.
