Tough call.
It's been an hour since you posted, any changes since then?
They all look like they are breathing so I, personally, would leave them to get out on their own.
Wait. Sit on your hand and don't borrow trouble. ;)
Assisting is for way(relatively) past day 20....
.....and only when absolutely necessary.

These temps are too low.
The most important thing to do before incubating is test/calibrate your thermometers and hygrometers. I've found a good food thermometer is the best for comparing to others.

Here's some...
Be very careful with this.
I've had a chick with it's eyes 'gunked' shut, wiped with warm water on cotton ball repeatedly to get gunk gone. But it was up and moving a day or two old.
Is the abdomen closed?
Double yolk egg?
Now on day 11?
Am guessing you won't need to know as they won't live much longer.
Sorry, but it's very very rare for double yolk eggs to actually go full term and hatch.
Normal for them to be wet right after hatching.
Humidity spikes big time after each chicks hatches,
but should come back down in a few hours.
Hard to know what the 'red cord' is.
This is what I would do.
Take the 6 'older' ones out and put them in the brooder.
Leave the 4 and take a look at the pip.
Hopefully you have some ointment or coconut oil on hand to moisten membranes if needed.
Maybe you've seen this, but...
...not a good idea anyway.
If you are experienced at assisting, and have an incubator to keep it warm while it finishes hatching, a brooder to keep it warm afterwards, you might give it a try.
But then you'll have to get it back with the others which might be tricky.
