First picture is some kind of Lasius species i think.
Second one is a male from a Myrmica species, i think. :)
that first is surely some parasite lasius ... chtonolasius or what :P ... and in that male I am not sure , could be Myrmica male , - it is myrmecinae male , but not sure really which one , aphaenogaster and myrmica has similar males , also other species males are similar to these ones
