By mass or volume, in our solar system Jupiter is the planet with the most helium, the fraction being about 10% of its composition (or a quarter of its mass). The smaller planet Saturn by comparison is believed to be about 3%. There are of course many extrasolar planets identified (orbiting stars other than our Sun), which are known to be gas giants and have much larger quantities of helium in them (including one which is about 17 times as large as Jupiter), but composition is hard to estimate with accuracy at such great distances.

Jupiter and Saturn.

Uranus and Neptune have a rather different composition. Their atmospheres are mainly hydrogen and helium, but below that the composition is very different from Jupiter and Saturn.
