Lucifer being a angel exist in a state of full knowledge. Time as we know it is linear, but for God and Angels it is simply a state of being.
Lucifer being one of the Arch Angels was condemned when his choice to rebel against God the Father was made. Hell according to some Catholic teachings is a state of being apart from God. So in that sense one can be in Hell as long as one is separated from God.
It is one goal of all Christians to be in God's grace, to experience the beatific vision. Or as other religions call it obtain enlightenment.
This is of course dogma and alternate viewpoints of Catholic teachings.
