1)what is the total amount of places per country (by places I mean village, city, hamlet, etc). The count does not have to be split out, just one number per nation. And how do I figure this number out on my own for future reference?

2)I was told to run a overpass turbo query to extract specific features I wanted to review. How would I run it, or create it based on this information:

nsroadimport #thailand, source = digitalglobe and import = yes

Here's a sample script for counting the place features in a country:

(click on show data when the warning pops up)

The geocodeArea:Thailand is a feature of the Overpass Turbo website, to do the query directly against Overpass API it needs to be replaced with a reference to the OSM object the Overpass API area object is created from:

A query like area["name:en"="Thailand"][admin_level="2"]->.searchArea; should also usually work.

Overpass API doesn't support queries against changeset tags, but if the tags are on the objects you want to review, just putting something like import=yes and source=digitalglobe into the Overpass Turbo wizard will return objects with those tags. There are some resource limits on the public instances, so queries returning a large number of objects may time out. Limiting the query to some smaller bounding box is one way to deal with that.

Seeing how place is sometimes used, the more interesting query probably also checks for name.
