We use French Wikipedia here, as neither English Wikipedia nor Dutch Wikipedia include Ivan Graanoogst.

This one is slightly awkward, in that there have been a couple of different entities (People’s Republic of Angola until 1992), and several switches between the Prime Minister and the President being the Head of Government. Wikidata only currently knows about the latter, however.

This should probably be split across separate items for the Chairman of the Council of Ministers and the Prime Minister, but currently isn’t modelled like that.
