Use mail-archive and search the user mailing list and you'll read lots about ruleflow, agendagroups, semaphores etc. 3) can rules communicate across .drl files rules do not communication, they match data and fire rules. 4) is there support for looping and collection Drools has the most advanced LHS syntax than any other engine. with support for both collect and accumulate with accumulate functions - look into those. Any valid Java or MVEL statement can be used for the RHS.
