>how common is it for different species of whales to mate ?

I can't say whether it is common or not.  It is likely that there
is not enough information yet to make a blanket statement like that.
There does not seem to be much information in the literature about
hybridization that I can find.  In Blue Whales (Calambokidis and
Steiger) there is mention of a hybrid fin/blue whale that they have
observed.

Robin Baird documented a hybrid Dall's and harbour porpoise:

Earthtrust describes an instance in which meat from
a hybrid blue/fin whale available in Asian markets:

Phil Clapham stated in a Marmam posting that blue/fin hybrids
are extremely rare, and he cited two papers addressing blue/fin
hybridization:
