With Silver's Single Key (1 of 1), you have a Single Key (not multisig) that is stored on your phone and can be used for receiving, storing, and sending small amounts of bitcoin for everyday use.

Only this single mobile key is needed to spend funds from the app.

The Single Key is encrypted and backed up seamlessly to Apple (for iPhone users) or Google (for Android users)

With Gold's basic multisig (2 of 3), you have, in addition to the Single Key (not multisig) a multisig keyset with 3 keys. These keys, by default are a Mobile Device Key (stored on your phone), a Hardware Device Key (a Trezor or a Ledger), and Casa's emergency recovery key. You can optionally add a second Hardware Device Key in place of the Mobile Key.

Two of these three keys are needed to spend funds.

With Platinum and Diamond's advanced multisig (3 of 5) you have, in addition to the standalone Single Key, a multisig keyset with 5 total keys. These keys, by default, are a Mobile Device key (your phone), three Hardware Device Keys (two Trezors and a Ledger), and Casa's emergency recovery key. You can optionally add a fourth Hardware Device Key in place of the Mobile Key.

Three of these five keys are needed to spend funds.

Since you need multiple keys to spend funds from your Casa wallet, the key that Casa holds for emergency recovery cannot by itself be used to spend funds. This way, you don't need to trust Casa, but can still use Casa to help you spend funds in the unlikely event that you lose access to your own key(s). 

At the Diamond level, there are even more features like team signing and integrated inheritance planning through Casa Covenant.
