How much volt and amps would be in this CT circuit?
How many amps would be in Is?


Without a burden resistor on the output of the secondary there is zero amps


  How many volts is Vs?


This cannot be determined with knowledge of the core material. If there was a proper burden resistor, this can be determined.


  Does that voltage depend on te number of turns like current?


The voltage depends on number of turns and the burden resistor.


  Can I operate a 24VAC or DC relay from it?


Usually not or even hardly ever - the point here is that the burden resistor is typically a few ohms of resistance in order to prevent the core from magnetically saturating AND, the output voltage produced is around a volt RMS.
