I am a noob as well, but most say go with a hollowed round edge. The only one you have that looks like a usable blade with a round edge looks to be more of a wedge shape to me # 5. IMHO #1 in your pictures looks like the best bet 4 and 6 look ok as well. You might want to pick them up with a shaving hold and pretend to shave with them off of your face and see what is most comfortable as well. You could also have whoever honed it tame the tip down as well if you are concerned with that.
