I'm thinking the first one is a male as it gets a very black beard when his running around like mad on the floor chasing the daughter and the other two.
If anyone could help sex them it would be greatly appreicated.
Those photos dont really show a great deal other than the second one is a def female due to the vent width being narrow. females also get really black beards when angry ect.
I'd say male,female,male as a roughie.
If tany have large femoral pores going down the inside of the back legs then its male.If you fold the tail back over a bit more you might be able to see the hemipenes
