I think

Male due to extent of red on head and black nasal bristles. Also dark wings.

Male

Looks like it, on the amount of red behind the eye.

For non-ringers, females tend to have the red above the eye with a concave edge, where in a male it tends to be convex, as in this bird, extending beyond the rear edge of the eye. Not always reliable, but usually works.

Nasal hairs (male=black, female=grey-black) I have problems with...it takes a really close view and I am poor at colours. Well done to anyone who can sex a Goldfinch in the field on nasal hair colour!!

The reference to dark wings is the lesser coverts on the shoulder, which are black in a male and brown edged in a female. They are rarely visible on a perched bird, however.
