The best is to have two layers to swap diff signals. On 1 layer, only the option is to try to rotate components somehow, use different components with... -

Be sure, dielectric 2 an 6 are thin (much thinner than Dielectric 3 and Dielectric 5). Also, depends on what you are going to route on this.

Depends on memory controller capabilities. As Paul van Avesaath mentioned, you need to read datasheet.
For example:
