Yes you can. Highlight is a term for lightening the hair so you will have to use a lightning product to achieve the best results as permanent color will not lift the semi permanent color to the right level, but be sure to read the instructions and apply properly.
You cannot go lighter on colored hair with more color. If your hair has no permanent color on it, you use high lift developer. 10 volume for every level lighter you want to go. If there is color on it, you'd have to lighten your hair with bleach, then color it. Your best bet is to get it done professionally.
Developer is used with professional color to adjust level of color desired. For example, black hair could be described as level 1, adding blonde highlights would require a 40 volume developer to lift the color of your hair 4 shade levels.

10 volume is if you want to go dark with color but with bleach 10 vol gives you one level of lift but if it seems slow to you use 20 volume, never use 30 vol or 40 vol on scalp it will irritate it.
