There's an assumption that I've used in the first five scenarios, where you've said "I have Divine Challenged an orc in the previous round who is five squares away."
The assumption is that you have engaged that orc in the previous round - either you attacked him or were adjacent to him at the end of your last turn (meaning he's five squares away because on
his turn, he moved away from you). Otherwise, you can't use Divine Challenge this round on anyone, because you failed the conditions
last round, and have temporarily lost your Paladin Club Privileges.
1) Combat is raging. I have Divine Challenged an orc in the previous round who was five squares away. This round I went up and charged him. That ends my turn.

Assuming you engaged him last round (with a ranged attack, presumably?), then you have also engaged him this round, and you don't lose DC.
If you
didn't engage him last round, then you lost DC at the end of your last turn, so the scenario is nonsensical.
2) Combat is raging. I have Divine Challenged an orc in the previous round who was five squares away. He came up and thwacked me. I thwacked him back. I rechallenge him. I end my turn.

Again, assuming you engaged him last round, then you have also engaged him this round. Why are you "rechallenging" him? The existing challenge is still in effect.
3) Combat is raging. I have Divine Challenged an orc in the previous round who is five squares away. This round, I charge him and then Divine Challenge someone else.

Again assuming you engaged the initial target last round.
Are you spending an action point to challenge? Otherwise your turn ended when you completed your charge - you can't challenge after a charge without spending an AP. Let's say you are.
If you happen to be adjacent to the new target, you don't lose DC. If you aren't, then you have neither engaged the new target, nor challenged a different (to the new target) target; DC is lost.
4) Combat is raging. I have Divine Challenged an orc in the previous round who is five squares away. This round, I don't attack him but Divine Challenge him once more and end my turn still 5 squares away from him.

Again, assuming you engaged him in the previous round... why are you Challenging him this round? You still have a challenge in effect on him. Regardless, you are neither engaging him nor challenging a different target; DC is lost.
5) Combat is raging. I have Divine Challenged an orc in the previous round who is five squares away. This round, I ignore him completely and then Divine Challenge someone else. I end my turn.
Do I lose Divine Challenge?
Again assuming you engaged the original target last round. Yes, you lose Divine Challenge (unless your new target is adjacent to you). You are not fulfilling any of the requirements of the new challenge.
6) Combat hasn't started. On my turn I Divine Challenge an orc and engage some other target, with the orc still five squares away when I end my turn.
Do I lose Divine Challenge?
Absolutely. You have not challenged a different target, nor attacked your target, or ended your turn adjacent to your target. Divine Challenge Fail.
7) Combat hasn't started. On my turn I walk up to an orc, hit him and then Divine Challenge someone else and then end my turn.
Do I lose Divine Challenge?
Absolutely. You have not challenged a different target, nor attacked your target, or ended your turn adjacent to your target. Divine Challenge Fail.
