But this filed has 8 bits (only 256 values). What exactly would it happen if radiator has more that 256 pending request from AAA server? Does it creates any misbehaviour?

yes that is a very real possibility that effictively limits your request/time rate to 256 / time_for_backend_to_answer_a_request.
So if your backend is a far away you have to account for network delay which further reduces your requests/s.

See section 5.30.20 in the manul on UseExtendedIds on how to fix this for most modern radius servers that support the Proxy-State Attribute.
