No, they are different!
yes
yes they are same.
No, ray CD and ray DC are not the same. A ray is defined by its starting point and extends infinitely in one direction. Ray CD starts at point C and extends through point D, while ray DC starts at point D and extends through point C, thereby having different directions.
If you mean CD plus DC then in Roman numerals they add up to M meaning 400 plus 600 = 1000
yes
No. Line CD is the same as line DC, but rays are always named from the origin point, so ray DC is a ray pointing in the opposite direction from ray CD.

yes they are same.
Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.
They define the same line segment, connecting two points.
