Can I have more than one account?

Yes, if your wallet came from a seed phrase. Go to Manage wallet → Accounts to add, rename (up to 25 characters), hide or switch accounts. Every extra account comes from the same seed phrase, so your one backup still covers all of them.

Hiding an account only removes it from the list. Its key and funds are untouched. Accounts cannot be deleted one at a time, and you cannot hold two different seed phrases in the app at once.

A wallet imported from a private key has a single account.
