I read a few questions there were related to this, none that i encountered seem to give me an answer.
I am using SDK15.1 nRF52
I am NOT using dynamic allocation, I need something that fetch the size of RAM/Application stack at runtime. and Is it possible if the size isn't enough we can increase it?
(I am trying to not use dynamic allocation according to the requirement given to me but do let me know if that's the ONLY way to do it.)
So why do you want to know this?

No!
The size of the RAM is a physical feature of the chip - it's not like a PC, which you can open up and add more RAM.
These settings are part of your Project configuration, so they are known at build time - hence it's not generally useful to query this at runtime.
So, again, why do you want to do this?
Often linkers have facilities to pass information back to the code; eg, for Keil:

For total RAM size, you can look at the INFO.RAM register:
No worries. If it resolves the question, please verify the answer:
