getclicking.co.uk - quite memorable, but you'd have to spend a lot on advertising to get people to visit it. The domain in itself isn't that valuable IMO. Perhaps suitable to a discount or cashback site.
casino-group.co.uk - Has the word casino in it, which is an intensely competitive high paying sector, but other than that there's nothing that exciting about the name. Developing it into an affiliate casino site would probably be the best option, I can't see a high sale value unless there's a company called Casino Group.
mobilogomusic.co.uk - Not really valuable, too long, too unspecific. What was the thinking behind this domain?
get-rated.com - getrated.com would be a very brandable name, suitable for a hotornot type site. So quite a lot of potential there. The dash separated is much less valuable, but develop it into a hotornot type site, then with the proceeds, make an offer for getrated.com
Just my opinions .... hope this helps.
