Hi Ricardo,
To answer your questions,
1. I would use the following query to get the info you need.
SELECT ?item ?itemLabel
WHERE
{
?item wdt:P31 wd:Q6256 ;
rdfs:label "Portugal"@en .
SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}
2. There are a few ways to SPARQL most used properties, but the size of the
graph will definitely time out. You may want to start with the Wikidata
Property Explorer <https://prop-explorer.toolforge.org/>.
best regards,
Darnelle
