How many endings are there in Silksong and can you do all of them in one save?

I am 24 Hours into the game in Act 2 just started the main quest to find and learn the Threefold melody and already got the architect melody. I am having fun even though its a bit tedious its still a fun game and Im wondering how many endings there are in Silksong and if you can get them in 1 save file/playthrough like in Hollow knight where the only missable ending was when you dont fight the boss with Voidheart
