The orbital velocity of the artificial satellites revolving around the earth is,

\[v=\sqrt{\frac{GM}{R+h}}\;\;\text{or}\;\;v=R\sqrt{\frac{g}{R+h}}\]

From above relation, it is clear that the mass of a satellite has no effect on its its orbital velocity. If they have same orbital radius, then $R+h=r$ will also be same for them. Thus, the speed of the satellites should be same.
