Depends, of course, where in East Sussex. From Eastbourne to the outskirts of London (Croydon, for example), you can drive it comfortably in one hour 20. Using the train, the journey takes around one hour 30 to London Victoria (which is reasonably central).
That depends on where in Sussex. London-Brighton is about 51 miles.
London is a city and Surrey is an adjacent county so it depends on which part of London and which part of Surrey.
It would depend on which part of London and which part of Sussex but probably a maximum of three hours.
About 1 hour and 49 minutes.

If you are refering to Crawley, Sussex, you are way off. Although it is not a part of London, it was built for a settlement to ease congestion in London, I believe. It is many miles North of Brighton, South of Horley in Surrey, North-east of Horsham. It is also just south of London Gatwick Airport, on the Surrey-West Sussex Border but on the Sussex Side. I hope my answer has helped you slightly. Good Luck.
