Yes they do! The low pressure compressor (N1) and low pressure turbine (N1) are connected by a shaft, so they always turn the same RPMs.
The N2, compressor and turbine are connected by a shaft so they (high pressure compressor and high pressure turbine) turn the same speed but the N1 and N2 turn independently from each other.

In a twin spool turbofan engine, N1 is the low pressure compressor. N2 is the high pressure compressor.
There is no mechanical conection between the two. Only airflow from one to the other.
The N1 will rotate at a slower speed, mainly because of more mass.

Yes because they are mechanically connected. The N1 spool is typically the low pressure compressor (the front ones) and the low pressure turbines (the aft most ones).
N2 is the high pressure compressor and high pressure turbines and they will turn faster than N1.

The twin spool compressors turbo jets are having two different sets of compressors. the low pressure compressor N1, and high pressure compresor N2.
Similarly they have two sets of turbine, high pressure and low pressure, which are connected to there respective compressors. these sets work indipendently i.e the low pressure compressor is at same speed with its turbine, where as high pressure turbine is at same speed (and driven by) its respective turbine.
Hope this will help you .

yes they are going at the same speed...if they are not, the shaft that is holding the compressor and turbine is broken.

As another former FE , I can confirm the previous answer is correct.
