Male or female

Hi this is my first time growing and I can't tell if my plants are male,female or hermaphrodite any help would be gladly appreciated. If they are male or hermaphrodite what should I do with them? (total of 3 plants)

 

Are all 3 of them male? Cause only 2 of them I saw have balls damn

 

damn.... What can I do with all males unlucky

 

Thanks I've cut down the males hopefully I get lucky my last one can be female. Cause these were just seeds I found in my old dealers buds.
