Great question!
Sequelize is an ORM (Object-Relational Mapping) package for Node.js that works with a variety of SQL based databases such as Postgres, MySQL, SQLite, and a few others.
SQL is a query language used for querying and interacting with a variety of databases.
NoSQL is sort of an umbrella term for any database that doesn't use SQL for querying the database. Most frequently it's used to describe databases that don't rely on the legacy, tabular data format that SQL databases do.
MongoDB is a document database that has its own query language and stores data in, more or less, JSON. It is a cross-platform, modern database that falls into the NoSQL classification.
I hope that helps somewhat but post back if you have any further questions.

Just to be clear, the term "nonrelational database" is a bit misleading as all data does indeed have some relations built into it. NoSQL databases can definitely handle relations. Neo4j, as just one example, is a NoSQL graph database that handles LOTS of different relations between nodes.
Keep up the great work, and happy coding!
