I want to know all kanji with the radical 亻
I'm not sure that you actually want to do this.
Firstly, I think it's helpful to clarify what a radical actually is.
A radical (部首) is a section (部) header (首) of a dictionary. It is exactly analogous to the first letter of an English word - they are both just dictionary indexing tools.
Wanting to know all kanji with the radical「亻」is like wanting to know all English words starting with the letter「Ａ」. I'm sure that you'll agree that this is not the most helpful way of learning English (or kanji).
Perhaps, instead, you meant that you want to know all kanji containing「亻」as a character component. Given the long history of kanji and how they have changed over the years, there is not actually a reference (as of early 2019) that tells you all the kanji containing some component X. Two major reasons are:
Kanji components change shape depending on where they are found in the character. The stand-alone shape of「人」is a side-view of a person.
Kanji components may have fused with other components, so in some characters you can't actually tell them apart in the modern script anymore.
