I'm going to answer your last question first:

what are examples of Design records
In common parlance, "design record" is synonymous with "engineering drawing" although the term is also inclusive of specifications and requirements that might be only referenced on the drawing, or even requirements expressed in a purchase order. The design record is all of the specifications and requirements required to produce the product in question.

2)Product Control Plan Dim 12±0.5 is the process dimension and actual Dim to be achieved is 12±0.1;
I don't understand the distinction you're making--what's the difference between "process dimension" and "actual Dim to be achieved"?
GaneshKumar.Vatturi said:
In drawing also same dimension is addressed ie.,12±0.1
The specification on the control plan should match the one on the drawing, unless you're deliberately making the tolerance tighter, or there's a subsequent operation that achieves the final (drawing) dimension, as in the case of a turning operation that's followed by grinding. It's OK to have process dimensions that are different from the drawing dimensions when it's necessary in a multi-operation process.

3)Product control plan now specific dim is addressed but the drawing there is a over all reference dimension 105±1 which is not addressed in the control plan
Whether or not reference dimensions are included in layout is a subject of minor controversy. The AIAG PPAP manual, 3rd Edition, states in a note ("...for guidance in understanding or clarifying the associated requirement") that,
All dimensions (except reference dimensions) characteristics, and specifications as noted on the design record and Control Plan should be listed in a convenient format with the actual results recorded.
Some customers expect reference dimensions to be included in dimensional reports, however.
GaneshKumar.Vatturi said:
so in this above three situations how we have to demonstrate this clause do we have to follow as per product control plan or as per design records
Yes. If there are control plan requirements that are not on the drawing, they should be included in dimensional reports, as should all drawing specifications and requirements, with the possible exception of reference dimensions.
