In the Bible, Satan is the devil; that's the adversary.
There is evidence that it is better to not slander the devil according to Michael's example in Jude. Just say "The Lord rebuke thee." That's our biblical example for responding to the devil.
Should you pray for your enemies? Yes, but praying for the devil assumes the devil can be redeemed, however the devil can't be redeemed for it is written the devil will go to the lake of fire to experience the second death.
Jude 1:9
9Yet Michael the archangel, when contending with the devil he disputed about the body of Moses,
durst not bring against him a railing accusation, but said, The Lord rebuke thee.
