how can add pc matherboard and laptop ram socket hole ddr1 and ddr2 and ddr3 and ddr4
You Ior someone) would need to create a part for the motherboard you wish to use (as they are all different.) As far as I know no one has done so, because it isn’t particularly useful in Fritzing, but it could be done, if not easily.
Again you (or someone) would need to create a Fritzing part for an appropriate socket, again I don’t know of an existing part. DDR ram has I believe tight layout rules (all traces the same length and same path to minimize skew) and thus Fritzing may not be the best choice for whatever you are trying to do.
