MRAM has so far been primarily a competitor to SRAM and NOR flash, but definitely not to NAND flash. ReRAM as an embedded memory will be competing in a similar space, but as a discrete memory will probably be most comparable to 3D XPoint.

I assume MRAM and FRAM refer to the same thing? If so Texas Instruments have some pretty cool (I think) microcontrollers using FRAM allowing for a user defined spit between volatile and non vatime memory, the MSP430FRxx series, I don't think they have it in any ARM parts though.

No, FRAM is quite different from MRAM. A FRAM cell has a single ferroelectric element that is read destructively (just like magnetic core memory). A MRAM cell has a pair of magnetic elements and resistance through one of them varies depending on whether the magnetization is aligned with the other element. That resistance is measured non-destructively.
