A chord is a set of three or more notes played at once. Here you can see the position of the fingers for the chord you want so you can play them on your guitar:

American Key: A = La / B = Si / C = Do D = Re / E = Mi / F = Fa / G = Sol / M = Major / m = minor
I recommend that you practice in this order: La.m, Re.M, Sol.M and Do.M .Then practise all the others. Those with a line called consistent with eyebrow, and are very difficult, I recommend you leave them fo later. Before continue I suggest you to practice time with this, and then start with the harder ones.
