Answer 1

The Jena Ontology API is great for getting individual classes, properties, and their details and relationships.

SPARQL queries are great for querying a large number of instances and filter out only the bits of information (including their property values) that you need.

For your other questions, reading a bit of the documentation might help! The answers are in here:

• Intro to RDF and Jena
• Ontology API
• I/O Quick Intro
