Is it possible to make payment channel by both participants' funding? For example, I fund 2mBTC, my friend fund 1mBTC, then open channel.

This is currently being specified by all implementations. One the spec is finalized we can implement it.

In the specific case of connecting with a trusted friend, the friend can pay you 1mBTC onchain, issue you an invoice for 1 mBTC, then you open 3mBTC to your friend and pay back the 1mBTC invoice.

There's an open PR specifying exactly this kind of behavior on the rfc's repo lightning/bolts#524
