Yes, the first picture could be a male, as the red is very bold and seems to stretch behind the eye. The second picture looks less convincing, though. Some females can be very similar. In the hand, I tend to use the colour of the lesser coverts, together with the pattern of the red. I assume you were using the extent of red to sex it as a male?

Yes, I thought it just too much red for a female, the second could have been a juvenile.
Not a juvenile, as that would have a pale head at this time of year. Possibly you have a pair shown, or at least a male and a female. To be honest, though, you need a good view and you need birds which are really boldly one sex or the other. Many cannot be told apart in the field. I reckon the left is a male, though.
