Answer 1

Mongoose handling connections via connections pool http://mongoosejs.com/docs/connections.html

You can use server: {poolSize: 5} option for increase/decrease pool (number of parallel connections)

If you need connections to different databases look here Mongoose and multiple database in single node.js project

Example of multiple connections:

var mongoose = require('mongoose')
var conn = mongoose.createConnection('mongodb://localhost/db1');
var conn2 = mongoose.createConnection('mongodb://localhost/db2');
var Schema = new mongoose.Schema({})
var model1 = conn.model('User', Schema);
var model2 = conn2.model('Item', Schema);
model1.find({}, function() {
   console.log("this will print out last");
});
model2.find({}, function() {
   console.log("this will print out first");
});
