I dont think so

Based on the wording, I do have a little confusion: "If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to mark a new creature."

To me, this means that if the target of the HM disappears into another dimension and does not drop to 0HP, the HM remains on them for the duration of the spell and can't be moved to another enemy. Or, if you put the HM on someone then realize they aren't an enemy, you're stuck with it (unless you kill this non-enemy).

I would agree, in both of those examples, the creature is still under the effect of the spell.

In the second case, you can end the spell early (because it's a concentration spell, and you can willingly drop concentration on your own spell at any time) though you don't then get the opportunity to shift it to another target.

I argued this once with my DM and they said that it doesn't know and also that there is no "visual feedback" so it isn't seen, only you know it and only you can tell it's a mark of any nature. Imagine it being outlined though your eyes only.

It says for the damage type; Bludgeoning, Piercing, and Slashing. Does that mean you can choose the type?

No, that's just a quirk of how D&D Beyond has the spell classified. Since it just says "extra damage" is applied when you hit with a weapon attack, the extra damage is the same type that the normal weapon damage is.

Behold: 2024 Ranger 

I use this spell as a domian keeper cleric. You use this spell as a ranger. We are not the same.

If I use the two weapon ability as a ranger us the hunters mark would i get 1d6 or 2d6

What exactly does "If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to mark a new creature" mean? does it mean that if the enemy dies you can just move the same mark onto a different enemy at the cost of no additional spell slots or no? because Hunters mark is already a spell that you cast with bonus action so it seems redundant to state "mark a new creature" if your just recasting the spell but would make more sense if it was using the same spell (within the same hour).

I flavor as my ranger does the evil monkey point from family guy and says "your next"
