I think the list you wrote are all an okay substitute except for the boiled water. I would skip that one.
Of the 5 I think I would select #4 as the best option. Others may think differently.

i did try to copy somebodies advice about 7 different rooting hormons and they look alike(growing rosemary cuttings)so why the hastle.
