Have a look at the percent library.
It would be perfect for something like this, and would work for every device. You'd have to work out the percentage width, height, and margin for each PercentRelativeLayout relative to your person image.
Here's an example:
<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
app:layout_widthPercent="25%"
android:layout_height="100dp"
app:layout_marginLeftPercent="5%"
android:background="#ff0000" />
</android.support.percent.PercentRelativeLayout>
and remember to
compile 'com.android.support:percent:23.0.0'
