Help Identifying Male

Thanks for the quick responses everyone. I probably should have posted last week so I could have pulled it earlier. I'm pretty sure the other three are female, so that's pretty lucky.
 
Those pictures were all of the same plant. About it being healthy looking, thanks, but it was only the top that looked healthy. Lower fan leaves have been drying out and dying. That plant was the worst of the four in that regard. I'm hoping it's just happening because the lower leaves don't receive much light. They are in a narrow closet and the light distribution isn't optimal. The tops of the plant all look pretty healthy though.
