Hello,
I have the art of electronics and learning the art of electronics.
My question is: can i use Analog discovery 2 for simulating all of the labs and project in this great book?

All? That assumes that anybody around here has done all the experiments and, having thumbed through the book, that seems unlikely.
What you can do is modify the experiments as necessary for the equipment at hand. The 'recommended' prototype system is the Global Industries Proto-Board PB-503. It has a lot of nice features but in no way does it compare to the AD2.
One difference, the power supply voltages are limited on the AD2 so you may need an external power supply. Wall warts might be sufficient. Batteries are a possibility or you can just buy an inexpensive lab supply. This will almost certainly come up for Op Amps where you will probably need a +- 15V supply (I say without having read the manual thoroughly). Remember the ratings for the AD2, don't get carried away with higher voltages. Buy the BNC adapter and use 10x probes if necessary. It may not make sense right now but you lose the ability to float the scope channels when using the adapter and this severely restricts the differential capabilities of the AD2 - right down to where normal scopes work (without a differential probe). For the most part, if you are using the power supply from the AD2, you don't need the adapter.
What you won't find is more test equipment for the money. Just try to find something that will do what the Network app does: Bode' plots of magnitude and phase - this is critical to the study of filters and amplifiers. It also does a nice job for Fast Fourier Transforms - better than the Rigol DS1054Z within its frequency capabilities.
Having a dual channel scope is nice but adding a dual channel arbitrary waveform generator is really helpful.
If you have questions about how to adapt specific experiments to the AD2, just ask. There's always a way to get a similar result.
Here are some tutorials about the AD2

FWIW, the PB503 is a lot more money and has none of the important features of the AD2

Maybe the Digilent Power Bricks can help with the power source issue. Note that these are dual supplies so the 12V module gives +- 12V which might be perfect for most op amp circuits. +-15V would be better but the experiment can be scaled
I would use these with a powered USB hub. I'm not much into providing project power from my PC.
