I know blockchain.info - bitcoin
what i use for dogecoin, litecoin, Ethereum ?
I wouldn't suggest blockchain.info for bitcoin... It's an online wallet, you're not in charge of your own private keys, hence you are up to the goodwill of a private company.
If you're somebody who has a limited ammount of different coins, i'd go for the official wallets of these coins... The core wallet for bitcoin, litecoin, dogecoin, ethereum... Do be carefull tough, those core wallets sync and parse the full blockchain, meaning it'll take a lot of bandwith, storage and processing power to run them (especially the first time).
In case you don't have time, bandwith or storage, you can go for SPV HD wallets.
For bitcoin you have (for example) electrum and multibit HD
For litecoin you have electrum for litecoin
For dogecoin you also have a HD wallet
For ethereum => don't know
BTW: on android you have coinomi, it supports several (alt)coins.
