I have quite a bit to do with our dear chimney as the part above the roof is quite badly worn and much of the mortar has withered away and fallen off.
I'm largely inexperienced in this area.
How do I get the plaster between the stones without it getting messy where it shouldn't be?
I guess you should sponge off the excess with water.
Which mortar should I use?
Grateful for input.

Let someone who knows how to mason do the job. The stones need to be taken down to where they are secure. It's quite a simple task. The hardest part is building a scaffold that is good and doesn't damage the roof. We rebuilt a chimney 1m high 90*60 with 4 ventilation holes in 5 hours. We also cast a new crown, which is done in a special way. Now, our chimney was really bad, but the lime mortar used in the past was not good. We used regular mortar, have a stainless steel pipe for the boiler.
Well now, the asphalt is blooming, no mushrooms with water on the chimney!
Seriously. It's quite interesting what condition the top of the chimney and its bricks are in. Is it holding together properly, and how do the joints look in the channels? Most likely, rebuilding is the most suitable.
If you're going to apply mortar, take some time to scrape out everything that's loose with a knife and maybe a hammer, brush away loose material with a dry brush. Then mix the appropriate mortar to be quite stiff but not too dry. Bring a bucket, a tuck pointing trowel, one or two joint trowels of suitable width, and a façade brush. Take mortar on the tuck pointing trowel, hold it against the bottom edge of the joint you’re filling, and slide the mortar in with the joint trowel, little by little, ensuring it fills properly. Fill the joint slightly overfilled.
Continue until what you started mortaring has hardened a bit. The sections that are ready to be worked on, use the handle of the brush or the handle of the joint trowel to smooth down. Make sure this isn’t done when the mortar is too wet, as it will smear and appear too light. Once an area is complete, gently brush diagonally over this section. All done there, and just continue putting mortar on the next section.
Which mortar you should use depends on what your chimney top is built with, but I would guess hydraulic lime mortar or C-mortar because they "weather away." Bring plastic sheeting to lay down under where you're working to avoid getting the metal sheets messy.
Simple

Thanks for the spot-on answer.
I'll start by building a sturdy structure around it as we're also putting in a hose for the stove.
Let's hope we finish before winter
