3, #2, & #5 are my favorites. I think those three would work as is however if you wanted something more original... #5 would look more related if you used hexagons like in an actual bee hive instead of the contemporary shapes that really don't relate intuitively . I dislike the font in #1 and #4 simply because it has no character or complimenting style. I think the drip in #4 is too playful to market toward corporate clients. Also with the color added, I think it would look better on light surfaces if the darker yellow in the gradient was the focus.
