A tennis ball and a cricket ball are to be projected out of gravitational field of the earth. Do we need different velocities to achieve so?

no, both of them can be projected out of the gravitational field with the same escape velocity as escape velocity is independent of mass of the body which is being projected.
escape velocity =√(2GM/R)
where M is mass of the planet
G is gravitational constant
R is distance from the centre of planet
escape velocity =√(2GM/R)
where M is mass of the planet
G is gravitational constant
