How to make join for few columns in same table in postgres?

I have a table.
The table has several columns with user ids.
There is only one table with users.

If there was one column, then everything is clear, we do join user_id = users.id and then use users.name.
What if there are multiple columns? How can I do a join on each of the columns?

>Solution :

You can join the same table using different aliases.

select adduser.name as adduser,
    edituser.name as edituser, 
    deluser.name as deluser
from table as t
join users as adduser
    on t.adduser_id = adduser.id
join users as edituser
    on t.edituser_id = edituser.id   
join users as deluser
    on t.deluser_id = deluser.id
