Answer 1

you can add a tools section for each stage.

pipeline {
        agent any

        stages {  
            stage ("first") {
                tools {
                   jdk "jdk-1.8.101"
                }
                steps {
                    sh 'java -version'
                }
            }
            stage("second"){
                tools {
                   jdk "jdk-1.8.152"
                }
                steps{
                    sh 'java -version'
                }
            }
       }
}
