can I have multiple icloud accounts on one device

Welcome to the Apple Support Communities

You can add more iCloud accounts. Open Settings > Mail, Contacts and Calendars > Add account and choose iCloud

Welcome to the Apple Community.

You can only have one primary account, secondary accounts can be added at settings > mail, contact, calendars. Secondary accounts don't include photostream, find my phone and document syncing.

Are you sure only primary account can use Find my iPhone?

I added a secondary account to my daughters iphone and was able to use it for Find my iPhone.

It warns you that the Find my iphone service will be disabled on the other icloud account.

I think this is a good change so I can use a single account to track all the devices.

Looks like only photostream and documents/data are tied to the primary account.

Yes you are correct. Not sure whether that one just passed me by or whether its changed at some point.

Thanks for the heads up. 😎
