I know each sign represents a character of the show but i'm missing a few. The 6 finger hand is obviously the journal author, the pine tree is Dipper because it's on his hat, the star with the eye is Lil' Gideon, the strange symbol above the pine tree is Stan because it's on his fez, i'm not sure but I think the bag of ice is Blendin Blanden because the first time they made contact with him he knocked the bag of ice out of Dippers hands, the ? is Soos because it's on his shirt, the glasses are tricky it's ether sheriff Blubs or the glasses they find on carpet diem, the heart is Robbie because it's on his hoodie, the shooting star is Mabel, and I have no idea about the llama!
