Perhaps you really mean prediction intervals, since none of those results really a parameters. I don't think it makes sense to talk about 95%CI's in the context of a bagging procedure because there really is no single model. In any case it has already been suggested that this is not really an R coding problem but rather a conceptual problem. You were advised to post further questions on stats.stackexchange.com (if you were unable to find an answered question), the first hit on a Google search for "confidence Interval randomForest":
