Yes maybe
Yes, you can apply permanent hair color on top of semi-permanent hair color. Make sure that you do a deep conditioning treatment or hair masque before and after you color your hair.
apply all over
Yes, demi permanent hair color can be applied over any type of color. It will refresh the original color very nicely.
If the scalp is in good condition and was not irritated by the semi permanent color, it's OK to apply permanent color within 24 hours after initial color service.
you could, but it's probably not a good idea. because of the bleach, it is quite likely that the dye won't wash/fade out. But if it's what you want to do and you're willing to take the risk then go for it :)
It is recommended that you wait 4-8 weeks between color treatments because the chemicals can damage your hair and you need to give your hair time to restore itself. You can apply the semi permanent hair color a couple weeks later, but make sure to condition your hair well and check with your stylist before taking that risk.

To remove the natural color out of your hair and lighten it, you must bleach your hair. This is a difficult process and it can permanently damage your hair. You will have to buy a bleaching kit from drug stores and apply it to your hair. Black color hair after bleaching generally turns to orange or copper like color. You'll then have to dye to another lighter color of your choice. Multiple bleaches may be required before you can completely remove the black out of your hair. So in intervals of days re-do the bleaching to remove black color. Allowing sometime between bleaches helps your hair to heal and restore its strength. After bleaching, use milder dyes like semi permanent or demi-permanent so that doesn't further affect your hair. After a few weeks, when the hair color fades, you may apply a permanent coloring dye.
Impossible. You have two options though, you can simply wait for your hair to grow out, then chop off the dyed hair, or you can bleach it and then dye it your natural hair color or the color you desire.
