Here are the real answers if you take the Authorized King James Version Bible literally.
All went to different sections of a place called Sheol. Both the righteous and unrighteous. These verses explain it.
Psalm 9:17 The wicked shall be turned into hell, and all the nations that forget God.
Psalm 31:17 Let me not be ashamed, O LORD; for I have called upon thee : let the wicked be ashamed, and let them be silent in the grave.
Psalm 49:14 Like sheep they are laid in the grave; death shall feed on them; and the upright shall have dominion over them in the morning; and their beauty shall consume in the grave from their dwelling.
Isaiah 38:10 Therefore hell hath enlarged herself, and opened her mouth without measure: and their glory, and their multitude, and their pomp, and he that rejoiceth, shall descend into it.
Genesis 37:35 And all his sons and all his daughters rose up to comfort him; but he refused to be comforted; and he said, For I will go down into the grave unto my son mourning. Thus his father wept for him.
John 14:13 And whatever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
Psalm 6:5 For in death there is no remembrance of thee: in the grave who shall give thee thanks?
Psalm 16:10 For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption.
Psalm 88:3 For my soul is full of troubles: and my life draweth nigh unto the grave.
Isaiah 38:10 I said in the cutting off of my days, I shall go to the gates of the grave: I am deprived of the residue of my years.
Jesus then descended into Hades (Sheol) after his death.
Acts 2:27 Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One to see corruption.
31 He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption.
Ephesians 4:9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth?
Paradise (after Jesus paying for our sins) is now above not below.
II Corinthians 5:
6 Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the lord.
7 (For we walk by faith, not by sight:)
8 We are confident, _I say, and willing rather to be absent from the body, and to be present with the Lord.
9 Wherefore we labour, that, whether present or absent, we may be accepted of him.
According to these and other versus it seems the righteous (still sinners) and unrighteous all went to a place called Sheol which was below the earth and used as a type of spiritual prison. Jesus, after his crucifixion/death descended to Shoel to offer everyone there a chance at salvation. Many may disagree with me here but even though there are several references to “hell” and “eternal suffering” my take (and personal opinion here) is that what the Bible was really talking about here is those accepting of Christ during their lifetimes will still go to a pleasant area of Sheol while the unbelievers/or unrighteous will go to a less pleasant section of Shoel. At Judgement Day all the believers who were righteous will be allowed in the real paradise (above earth), the nonbelievers will be given a chance at to accept Jesus and a righteous life, some may not accept this gift however and choose to have their souls annihilated in the Lake of Fire along with Sheol because Sheol is only temporarily.
Those accepting of Jesus and a life of righteousness will be in the paradise which to me is really the new Earth being ruled by the Lord Jesus himself not heaven. Afterall according to the Bible everyone is supposed to be literally physically resurrected not spiritually. Those few who choose to deny Jesus and to live a righteous life for whatever reason will not suffer eternally in hell (Lake of Fire) but their souls instead will be annihilated forever (no awareness or suffering just oblivion) along with Hades (Sheol).
I’m not saying I believe all this stuff, my own religious views are way different from what any religion preaches but going by the Bible this is my own take and I will admit, personal opinion.
