This is the Reloading forum, not Gunsmithing or Rifles.
Anyway, it won't hurt a thing to leave Hoppes in the bore as long as you want.
But it won't do a whole lot of good either if you have heavy copper fouling.
For that, you need real Copper Solvent.
Hoppes makes Copper Solvent too, but that is not the same thing Hoppes #9 powder solvent.

Original or Bench Rest 9?
The original can be left in until you shoot again, as long as you dry patch it out. The additional amount of copper it will bring out will be marginal I bet.
The bench rest #9, if I recall correctly, states in the instructions specifically to leave it overnight, but should be removed before shooting.
So, yes it is fine.

"regular #9 is a poor copper remover"
True. That's okay because it doesn't claim to be a copper remover. But, even their "#9 copper formula" isn't much better.
Outter's has spray cans of a foaming bore cleaner that is inexpensive, harmless to steel and removes copper pretty well. Walmart used to have it but I haven't seen it locally since they "improved" the local store.

Original #9 is an 'adequate' copper remover if left in the bore for a while. It may not compare with the newer copper cleaners but it does eventually work.
It will not hurt the bore to leave it in, just need to patch it out before you shoot the next time.

I would not leave hoppes in over night. I have done so and had a hard time removing the film afterwards. The bore felt like it had a sun glazed coat of honey in it.
Brush w/ solvent soaked brush, wipe w/ jag/patch a few time, then clean w/ hoppes and jag/patch. If this does not clean, you need a better copper solvent.
I always remove ALL solvent, then oil w/ breakfree. Run dry patches until breakfreee is not noiticable on patch. Bore must be fouled before precision shooting.

Hoppes #9 works pretty good on copper, ya just need to be patient. If you have the space and time to let your rifle sit with the muzzle slightly pointed down for awhile, you may save some wear on your barrel by not brushing it as much later.

Hoppe's semi-auto solvent instructions say do not leave in the barrel.
It cleans (copper and crud) in my semi better than #9.
It's almost as expensive and hard to find as RF's air freshener.

Get some WipeOut. You just spray it into the barrel, let it sit and foam overnight, and in the morning all the copper is gone. You do need to get rid of the powder fouling first if you have much of that.

#9 does clean copper, if you leave it in overnight (which is ok).

Hoppes
Lay the gun flat so Hoppes does not drain out of barrel or run into the rifles action.
The longer the better, will not hurt a thing. It does dry out, so patch the bore every 2 day or so. In a hurry, use the Bench Rest Copper Solvent, this is used overnight, it will also remove plastic that is left in the chokes of shotguns or barrels of inline muzzle loaders. WARNING Do Not Leave Hoppes on Nickel Plated Firearms.

Just mix the hoppes 50-50 with Kroil and wet your barrel. Let it set overnight and run a patch through it the next morning. If there's copper in there, you'll see it!
The best Hoppes product I've used is the Elite Copper Terminator. It's a gel and works as good as an ammonia based solvent without the possible damage that ammonia can do to your barrel.
It does not produce the green/blue stain on patches like other Hoppes solvents, so it may not seem to be working. The patches come out a thick black/brown. I've found that the directions on the bottle are accurate and adequate to do the job.
I have double checked how well the Terminator works by using Benchrest (which does produce blue/green stains on patches) and found that there is no residual copper fouling after a standard treatment of Terminator. Good stuff in my experience.
I agree with everyone else that standard #9 is nearly worthless on copper.

Tip: Bore Brush-Cleaning-brass type. Rinse in 91% Isopropyl Alcohol when done. The brush will last a lot longer.

Absolutely, completely, totally agree 100%. Regardless, brass brushes are NOT a long term investment.
