Is there a way to see which kanji, vocab, radicals have achieved each particular level? I can see the numbers of each that are in each level but not specifically what is in there except how many of each
Do you mean like see a list of all Apprentice items, or all Guru or so on? For future reference these are SRS stages.
You can sort by SRS stage on wkstats (if you open the config). There are also scripts that can sort by various things, but I don’t know exactly which ones.
