I wouldn't trust assignment of anything to an Alexornithidae, as it was
originally concieved before enantiornithines were recognized and Kurochkin's
recent revival of the family is based on invalid characters-
> Alvarezsaurus (Late Cretaceous, Argentina)
Coniacian, according to Novas (1991).
> Apsaravis (Campanian/Maastrichtian Mongolia)
Campanian, as Ukhaa Tolgod is equivalent to Djadochta.
> Avisaurus (Campanian, USA, Argentina)
A.archibaldi Maastrichtian, Hell Creek Formation, Montana
A. gloriae Middle Campanian, Two Medicine Formation, Montana
A. sp. (Stidham, 1999) Campanian, Kaiparowitz Formation, Utah
The Argentinian specimen has been made the holotype of Soroavisaurus
australis, which is from the Maastrichtian Lecho Formation.
> Enantiornis (Coniacian, Uzbekistan, Maastrichtian, Argentina)
The Uzbekistani species are now known as Explorornis? walkeri and Incolornis
> Limenavis (Late Cretaceous, Argentina)
Campanian-Maastrichtian Allen Formation.
> Mononykus (Late Cretaceous, Mongolia)
Campanian Djadochta Formation.
> Nanantius (Campanian, Mongolia)
No, the Mongolian species N. valifanovi has been synonymized with Gobipteryx
minuta. The holotype Nanantius eos is from the Albian of Queensland.

Dromaeosaurids? Ha! Of course a paper is in the works, so I can't say more
>> Judinornis (Maastrichtian, Mongolia)

Yes, Nemegt Formation.
Also, you didn't include-
Horezmavis Coniacian, Uzbekistan
