Satan as the Morning Star: Satan was originally a good angel who then was cast out of heaven by his own doing. So we have the Morning Star (a good thing) being cast out of heaven (“How you have fallen from the heavens” and “How you have been cut down to the earth”)
Jesus as the Morning Star: by keeping Christ’s ways will share in His resurrection and victory over death, symbolized by the Morning Star
Lucifer, I believe is Latin for Morning star so the same would go for Lucifer.
Revelation 5:5 speaks of Jesus as the Lion of Judah. The lion being the traditional symbol of the tribe of Judah coming from Genesis 49.
1 Peter 5:8 speaks of the devil prowling around like a roaring lion looking for someone to devour
Lion in each case is being used to describe different things. In The Lion of Judah sense it means the more majestic and powerful attributes of a lion. The roaring lion looking to devour is in a negative sense of lion.
Revelation 16:15 “I am coming like a thief.” means we will not know when Jesus will return and to be prepared.
John 10:10 “A thief comes only to steal and slaughter and destroy” Again in a negative sense here just like the lion devouring above.
So in each case we can see that references to Jesus is in a positive way and references to Satan are negative.
