yes you can will it kill your hair yes but you can
Yes, but depending on the color you choose the highlights will always be lighter than the rest.
No, highlights are bleach which is different than color. Color coats the hair, while bleach removes pigmentation from the hair, to take out highlights you have to either color over them, or wait for them to grow out.
It is best to chose highlights that resemble your natural color because highlights bring out your natural color without drastically changing your hair color. Your hair will appreciate if you dye your hair less, but a few highlights may be just the ticket.
Yes, demi permanent hair color can be applied over any type of color. It will refresh the original color very nicely.
The best way to color over highlights is to bleach the hair and start over. This should not be done often.

Yes, but you can get a funky color if you do it wrong.

Splat hair color is not a permanent color it is a semi permanent color over bleached out hair, once the melanin (color) is removed from the hair the hair is very porous meaning it absorbs like a sponge and the cuticle of the hair is open so once you have put a semi permanent over it which just deposits that cuticle is still open leading to the color fading out!
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.
Do you mean pastel hair dye? It depends on if you use a permanent dye or a semi-permanent. Semi-permanent hair dyes will wash out and fade over time; permanent hair dyes will stay in the hair until you cut it or dye it another color.
