Is this the full list of premieres?
As of now yes, but more could be added if there's something on tap that they weren't ready to announce yet, like how April's Spider-Man premiere was added with a later update.

Do you know when the June Premieres will get posted?
They don't announce when they are going to send them in advanced, they get sent out when they get sent out, usually closer to the middle of the month.
