Q1.

To add an element in xml you need to place it inside a tag. Like so...

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
  <objectAnimator/>

</set>

Q2. To add a property, place the property and the value inside the same tag. Like so...

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator android:propertyName="y"/>

</set>

for Q3 and Q4, just keep adding the attributes in the question with the values in quote marks. Like so...

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
  <objectAnimator 
        android:propertyName="y"
        android:valueFrom="0"
        android:valueTo="400"
        android:duration="2000"/>

</set>

hope this helps
