How to configure Interrupt for all pins in ADC0 instance

Configuring CIMR0 and CIMR1 will enable interrupt for ADC0?

ADC channels are divided into 3 groups - Precision, Standard and External

Can we enable Interrupt for all ADC0 pins with CIMR0 and CIMR1 at once, if only precision and standard are used?

For CIMR0 & 1 register.

Specifies whether a completed conversion of a precision input flags an EOC interrupt.

Specifies whether a completed conversion of an external input flags an EOC interrupt.

For example: normal conversion mode.

At the end of each conversion, the result is stored in corresponding register(PCDRn/ICDRn/ECDRn),

the EOC flag is set and End of Conversion(EOC) interrupt is issued(if enabled in MSKEOC).

After the last conversion in the chain is complete, the ECH flag is set and End of Chain(ECH) interrupt is issued(if enabled in MSKECH).

So answer is yes, but you may need enable MSKEOC or MSKECH too for normal conversion mode.
