Can I use PWM(2 pin), Servo Library(2 pin), Tone Library(1 pin), Interrupts 0,1,2,3 and Analog Reads (A0-A3) at the same time on arduino leonardo??
No, not on any processor.
A pin can only be used for one thing at any one time.

If you mean, however, to ask if you can use PWM on 2 pins, Servo on two pins, analogRead() on 4 pins, and external interrupts on 4 pins, at the same time, then yes, you can. 4 external interrupts can be interesting to get working together, so good luck with that part.
