1. 'It will rain at times today' (every so often). 'At time' is not used.

2. Some time are an adjective and a noun; sometime is an adverb.

'I spent some time shopping.' 'Come and see me sometime.'

3. Same as 2.

'Give me some times when I could make an appointment.' 'I sometimes like to go swimming.'

4. Already answered.
