How can we get the local branch name in Jenkins job from which the Pull Request is raised?

Hi - there is no method for this in multibranch pipelines.
What I did is to use the CHANGE_ID to fire a REST call (in this case towards BitbucketAPI):

def response = sh(script: "curl --user $user:$pass -H \"Content-Type: application/json\" -X GET https://<bitbucketURL>/rest/api/1.0/projects/<prjKey>/repos/<repo-slug>/pull-requests/${env.CHANGE_ID}", returnStdout: true)
        def parsedResponse = readJSON text: response.toString()
        def branch = parsedResponse.fromRef.id.toString().trim()
