Do the Elf creatures put into the battlefield by Planeswalker Nissa Revane suffer from summoning sickness?
Yes,

From the Comprehensive rules:


  302.6. A creature's activated ability with the tap symbol or the untap symbol in its activation cost can't be activated unless the creature has been under its controller's control continuously since his or her most recent turn began. A creature can't attack unless it has been under its controller's control continuously since his or her most recent turn began. This rule is informally called the "summoning sickness" rule.


Any elf with Haste ignores that restriction as usual of course.
