So how many dimension does your “0 Dimension” have?
The answer to "how many?" is different when you deal with Multitude or Magnitude.
0 apples is based on the concept of Multitude, and in this case the result is the absence of apples.
0 dimension is based on the concept of Magnitude, and in this case the result is a point.
The Man said:
0 is however a magnitude and with a magnitude of 0 for dimension the number of dimensions being considered is, well, 0
"How many dimensions?" is a meaningful question which is based on the concept of Multitude, and one one the valid answers is "0 dimensions".
"How many dimension …?" is an invalid question, exactly as your reasoning about the "0 dimension" is.
The rest of your post is based on this invalid reasoning.
The Man said:
No, it can be used as magnitude or multitude, as clearly shown by this post.
The Man said:
0 magnitude is a lack of magnitude
No, 0 magnitude is, for example, length 0, and length 0 is a point, where a point is not the absence of the concept of length as "no length" is.
"No length" does not have a location (local or non-local), where length 0 has.

EDIT:
Maybe this can help:
Try to grasp the difference between "0 length" (which is the absence of length, according to your reasoning) and "length 0".
