Ideally, you would look at them under a microscope and see what the trichomes look like. If there are trichomes, then rip them out and use them for hash or cooking. The males have almost no THC, and using them to cook might be a complete waste but I usuallydo it just because I dont like to waste anything.
You could always make some rope out of them, and use the rope to LST your next grow. That would be pretty bad ass.
In your situation, since you dont have many leaves its not even worth the time to look for trichomes. I would deff get the one on the right out of your grow room pronto. The plant on the left doesnt show many flowers, well atleast you cant see them in the pic. If the other one has the little football things, then its a male and its needs to be eradicated. If those little footbal sacs have opened up, which im gonna go ahead and say they have, then you should do a complete clean of the grow room before starting another grow.
I dont know what you mean by throw them out, but if you live in the states, keep in mind once the trash hits the curb its public property.
