Answer 1

As you stated, When you write this,

mongoose.model('categories', CategorySchema);
mongoose.model('categories', TopicSchema);
mongoose.model('categories', ArticlesSchema);

The output becomes inappropriate so do this instead,

mongoose.model('category', CategorySchema);
mongoose.model('topic', TopicSchema);
mongoose.model('article', ArticlesSchema);

Bonus tip. Mongoose makes your collection name plural by default so change a little code if you want your collection name as you wrote.

mongoose.model('category', CategorySchema,'category');
mongoose.model('topic', TopicSchema,'topic');
mongoose.model('article', ArticlesSchema,'article');
