Choosing a Chinese name based on John the Apostle
You have done a lot of research, and picking a name is entirely your personal choice, there are no right or wrong answer to it, just good or bad choices. Bad choice means something that sounds offensive or taboo, e.g. 徐定富 means '徐 + certain to get rich'  but it sounds the same as 除定褲 (drop the trousers first) in Cantonese. Your four choices have no problem like that.

約翰 and 若望 are common transliterations of John. If you don't want your name to be too common-place and text-book, you can change to other similar-sounding characters

安約翰 --&gt; 安逸瀚
安若望 --&gt; 安若翰

安約安 sounds quite strange, almost like a tongue twist

安曜輪 is unique and sounds native, but 倫 is much more common and meaningful in names than 輪, so 安曜倫 would be a good choice.
