Can u advice some good online wallets please? 
Search for online wallets that operates in your country, in this way moving money in and out will easy. its also a good training ground when starting out with BTC,
Sometimes the first results of Google aren't always the safest. You need to watch out for scams. What the OP is doing is what everyone should do. Go to a site like Reddit, Bitcointalk or forum.bitcoin.com and ask for trusted programs.
Id recommend BitGo, as they are the most secure partially web wallet. Otherwise, I would say Blockchain.info.
