sure, if it doesn't obey hookes law then you can just do an experiment using a set of known weights to calibrate the spring (creating a force vs. displacement graph)
The only thing you need to be careful of is when you reach the elastic limit of the spring. If you put more weight on than this limit then the spring won't return to its original length and your calibrations will have to be thrown out.

yes u can still use it to measure forces.
considering that F=-kx is not valid then also uptil its elastic limit u can relatively compare its elongation with various forces. and constitute a new basic system with with a basic force as its minima and relative to it all weights will exert a pressurec which can be graphed down
