locations and other context

[fej4955]

Hello,

I have advanced to locations and objects. If anyone would like to correct this list, that would be great.

inside 안
front 앞
back, behind 뒤
side, next to 옆
left 왼쪽
right 오른쪽
left side 왼쪽 옆
right side 오른쪽 옆
top side, above 위
bottom, below (special) 밑
bottom, below (whole area) 아래

this one 이것
that one 저것
that one over there 저거
this object/thing 이+(object)
that object/thing 저+(object)

here 여기
there 저기
over there 저

where 어디

My questions are:
1. What is "which"(interrogative pronoun)? I mean now in these contexts of
a) Which one is it?
b) Which book is it?
2. What is "that object/thing over there"?
3. Is "next to" and "side" the same word?
4. Is there in Korean these following aspects?
a) closer to the speaker
b) closer to the listener
c) away from both speaker and listener
5. What is the difference between 밑 and 아래?
6. Is the "this"-part the same in Korean of these English words?
-This book
-This dog
-This man

Thank you in advance
