I am designing a FM radio receiver. Can anyone tell me show much power
can I receive from a FM station that is in a acceptable range? I need
that value to decide the gain of all the stages. Thanks.

You need *variable gain* to cope with the wide range of signals you're likely to
receive. The gain required for any given station is determined by the AGC
(automatic gain control) circuitry.

Wrong. FM broadcast receivers do not have AGC circuitry (unless
you're trying to keep the group delay through the receiver constant).

There are planty of FM receiver chips with AGC for FM.
