Answer 1

There is an example that shows how to implement a measure tool in OpenLayers 3, see:

http://openlayers.org/en/latest/examples/measure.html

How such a tool is implemented greatly depends on the application itself and the other libraries available around it. For example, you're using GeoExt3 and ExtJS6. You could create the tool as a GeoExt3 component and contribute it with Pull Request. See: https://geoext.github.io/geoext3/ (Now: Get Involved!)
