There is hades/sheol which is where unsaved sinners go to.
Before Christ, sheol was separated into "Abraham's bosom" aka a temporary paradise and sheol proper. After Christ's finished work on the cross, all saved people go directly to heaven.
During the second coming of Christ, hell, unbelievers, Satan, antichrist, false prophet and demons will be thrown into the lake of fire to be consumed.
tl;dr there's:
1. 3rd heaven or heaven proper, God's abode and all holy angels and saved people. Different dimension/realm.
2. 2nd heaven aka the universe, space, 3D world that we see.
3. 1st heaven, the firmament, our atmosphere, the sky. Satan was cast down to this place and he is the "god of the earth" ever since he deceived our parents in Eden.
4. Hebrew Sheol or Greek Hades, aka hell. This is where sinners go to when they die.
>yet to happen in the future:
5. Lake of fire, no one has gone there yet. This is the final place where death and sin is destroyed for ever.
6. New universe, new earth, new Jerusalem. Perfect paradise and Edenic conditions restored.
