Yes it is still possible.
Miners choose what transactions they wish to mine. Usually they choose to mine transactions that have the higher gas price in order to earn the most out of fees but they have no obligation to.
Possible, but extremely unlikely unless you have a "connection" to a miner. This means being a miner or being "friends" with a miner that has decided to mine your transaction instead of a more profitable transaction.
An alternative is How are 0 gas price transactions getting mined?
