Q: Do these bleed through on Bible pages?

I don't know the answer to that, but I wouldn't even TRY them in my bible (and I'm a Bible journaler!). I use prismacolor colored pencils in all my Bibles.

Q: Where can I buy refills for this pen?

You should be able to purchase refills here on Amazon

Q: Can you right on a rock with these?

I have not tried to do so, and I really doubt that fine of tip would work very well. I guess I would experiment to see if you could. They do make pens especially for writing and painting on rock. I would recommend that type of pen, but try these to see.

Q: Has anyone colored with these?

My uni ball Signo RT1 collection of color gel pens are of 0.28 mm fineness. They are very very fine point. At such fine point, I think you can only write with it. I think it will be hard to color anything with it.
