I have a few hex screws that i would like to remove. I bought a bit
for my drill at home depot and lost it on the way home. I remembered
that i had an old socket wrench set. Could someone tell me how this
works? I see at the 'head' of the rachet a turning figure, but don't
know its purpose.

Try the old car repair book, How To Keep Your Volkswagon Alive. It
shows all the basics and even warns the reader to not eat the wrench.
