ALL of the saved of all ages will be resurrected at the 1st Resurrection.
Daniel 12:2 summarizes the two very different fates facing mankind and says..............
“Many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.”
Everyone will be raised from the dead, but not everyone will share the same destiny. The New Testament reveals the further detail of separate resurrections for the just and the unjust.
The 1st resurrection takes place in
various stages. Jesus Christ Himself who is the “first fruits,” according to
1 Corinthians 15:20, paved the way for the resurrection of all who believe in Him.
There was a resurrection of the Jerusalem saints in
Matthew 27:52-53 which should be included in our consideration of the first resurrection. Still to come are the resurrection of “the dead in Christ” at the Lord’s return which is known as the Rapture in
1 Thessalonians 4:16 and the resurrection of the martyrs which you asked about which will be at the end of the Tribulation as seen in
Revelation 20:4.
