No. Because if the spren didn't all agree, then some of the Windrunners would have lost their powers. We see them all flying, holding stormlight, powering their Shardplate, etc etc. So all of their spren had to be in agreement.
And, if some of them didn't agree, they would have either told their friends, if only to say goodbye. Or tried those "other methods" Notum mentions to try and break their Bond.
