To the best of my understanding, there are three roles on Stack Exchange family websites who are able to delete a question:

  1. Moderators
  2. Voting users with reputation > 10000
  3. Question owners

Are there ways for non-owner users to find which question is deleted by which role(s)?

    Yes, in the timeline. (Click the clock button at the left under the voting buttons) but if you have < 10K reputation you need to be the owner of the post to see that (as only with 10K you can see deleted posts) – rene Dec 1 '20 at 6:39
  • @Glorfindel Does that duplicate really answers this question? I'm reluctant to cast a re-open vote as that will hammer it open and I rather not end-up with you (or any of the other voters) in a close/re-open war. – rene Dec 1 '20 at 9:11
  • @rene It doesn't really. The section What does deletion mean for a post? semi-addresses this question (it talks about the display of deleted posts on their former links), but I think this question asks about there being any ways to find out (other than on the former links themselves). As I don't have a hammer, I've cast a normal vote. – Sonic the Curiouser Hedgehog Dec 1 '20 at 21:07
  • @Glorfindel See my comment above. I don't really think this is a dupe. – Sonic the Curiouser Hedgehog Dec 1 '20 at 21:08
  • The answer does start at the section with the text: "Can I still see my own post even after it's deleted?" and is vaguely hinted to new users, and somewhat more clearly explained to seasoned vets, in the following few sections - so the dupe target is correct. --- That the FAQ should be clearer doesn't affect its status as the correct dupe; even if another is better such should be suggested and edited into the banner's list. – Rob Dec 2 '20 at 0:13

You can't easily do this for currently deleted posts. For any post the delete event is visible in the Post Timeline. It is possible to find posts that were deleted and later undeleted as those are in the Stack Exchange Data Explorer.

This query shows for once deleted posts if they were deleted by their owner. There isn't an easy to use (historical) list of moderators in SEDE so I didn't bother to check if the delete was done by a moderator. I have added one way to get moderators by looking at users who have applied postnotices as that is a mod only feature. That list isn't guaranteed to contain all mods. There might be additional ways to find mods. That is left as an exercise for the reader.

;with mods as (
select distinct owneruserid 
   --  , max(postid) as [Post Link]
from postnotices pn
inner join postnoticetypes pnt on pnt.id = pn.postnoticetypeid
where pnt.classid <> 2 -- Bounty
and owneruserid <> 152859 -- data bugs

select distinct 
       postid as [Post Link]
     , text
     , case 
       when p.owneruserid = voters.userid then 'owner' 
       when voters.userid in (select owneruserid from mods) then '(former) mod'
       else null 
       end [role]
from posthistory ph
inner join posts p on p.id = ph.postid
cross apply openjson(text, '$.Voters')  with (userid int '$.Id') voters
where posthistorytypeid = 13

Do know there is also a possibility to delete a post via review. When a post gets flagged as Very Low Quality or Not an answer in enters a review queue where reviewers can delete a post, if enough of them agree. Those reviewers don't need to have > 10K reputation or a diamond to make that delete happen.

More information on how deleting works is found in How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?
