I like the way, you use color to distinguish "Karin" from "Jorga". Even though I like #1, it is may be a little bit too playfull. I also like #8 as it has a person as symbol, indicating "life".
Entry #2 seems the least fitting, as for me it looks a little bit too much like "hospital" or "red cross". I also think that may be adding the company slogan ends up with too many words.
Hope this helps!
