In no particular order.
1. Logo - Not keen on the colours. But the design is clean.
2. Logo - I would have like to have seen this one evolved more than what it was.
3. Logo - Maybe the colouring in the font in this design can be recoloured but the overall design looks good.
4. Logo - Nice design but very choppy in places. Could be a problem if you plan on rescaling (an assumption) because I think the images have been rasterized.
5. Logo - Nice clean design. Not sure about the text "Keys to sucess" this could be removed for a cleaner/uncluttered look and further developed and adapted to compliment the new style.
6. Logo - Another nice design, Not sure about the text though this is easily changed for something that looks more appropriate.
7. Logo - Nice looking and creative look. Not sure about the colours though.
