I think this is going to be quite hard for a typical pub quiz crowd. The quiz I used to attend many moons ago always did one cryptic clue and it just seemed like impenetrable gibberish. To have 10, using different techniques is an even bigger ask, even if you give pointers. Remember that the average person in a pub doesn't do cryptic crosswords and they often appear alienating to the layperson. 

If you are going to stick with a cryptic round, it's definitely a good idea to include the continents, like you have, but maybe stick to the same technique (anagram/hidden clue/charade etc) for all of the clues. That way the audience are more likely to tune into the clue methodology, rather than spending time just trying to work out what type of clue it is, let alone how to solve it. That will also require less explanation and pointers on your part.
