Of course you can have more than one wallet

(mobile wallet, desktop wallet, hardware wallet, paper wallet, offline wallet and online wallet)
Certain wallets are known for the advanced levels of security like Armory or the original Bitcoin client (Bitcoin-Qt).
Most popular wallets are Mycelium, Xapo, Armory, Hive, MultiBit , Blockchain, Coinbase, Electrum ...
