There are apps that lock or hide files, but locking the phone is just about as secure. A password is a password. If it's strong enough it doesn't matter if you use it to lock the phone or you use it to lock a file.

But if you want to lock different things from different people, as I said, there are apps to lock or hide various files and apps. Look in Play. (And select a good password - 20 random characters, including upper case, lower case, digits and special characters. Of course you'll need a password manager to handle them, but you should already have one - you should never use the same password twice. Every app and every site should have its own.)
