OC sketch (+Help?)

First: these are just sketches of my Oc's. So ignore my ugly proportions, hands and shading  
These Oc's don't belong to any series, they belong to my imagination. 

thanks to everyone, who helped me with the names! there were really creative and helpful! if you have any other names, i would love to hear them, but i don't use them for these oc's anymore! thank you
