  By applying the conformal SO(2,4) transformations to the elementary one-cusp
Wilson loop surface we construct various two-cusp and four-cusp Wilson loop
surface configurations in AdS_5 and demonstrate that they solve the string
equations of the Nambu-Goto string action. The conformal boosts of the basic
four-cusp Wilson loop surface with a square-form projection generate various
four-cusp Wilson loop surfaces with projections of the rescaled square, the
rhombus and the trapezium, on which surfaces the classical Euclidean Nambu-Goto
string actions in the IR dimensional regularization are evaluated.
