Answer

Yes, it's fine, providing the context is clear. You could also use 'sunburn' as a verb and say 'I'm afraid of getting sunburnt.'.

Answer

Yes, you could say  'I am afraid of getting burnt'. as long as it is clear from the context that you are talking about sunburn, rather than some other type of burn.
It is 'sunburn' - one word.
