I am not sure what exactly you want to know, but here's some positional words.
앞: in front, 뒤: behind, 위: above / on top, 밑: below / under, 옆: side
왼쪽: left, 오른쪽: right, 어디 / 어느 곳: where
위에: on / over, 밑에: under / below, 안: inside, 밖: outside,...
You can say things like:

개는 어디에 있어요? Where is the dog?
개는 탁자 밑에 있어요. The dog is under the table.
