The ease of liquefaction increases down the group due to increase of atomic size and hence van der Waal`s forces.

He has the weakest van der Waals forces of attraction due to its smallest size and hence has lowest b.p. In other words, its liquefaction is difficult. As the size of the noble gas increases from He to Xe, van der Waals forces increase and consequently b.p. increases and liquefaction becomes easy.
