Hi.
What is the rulers for selecting the STM32_ST_IRQ_PRIORITY? Before I think that it must be as high as possible, i.e. 1. But now I see that it is default value for STM32 is 8. Tell me please how it must be.

It depends on your requirements, 8 is fine usually.

0, 1 and 2 are forbidden, like all other interrupts.
