Can I have multiple SPF records?

No. You must have exactly one SPF TXT record per domain. Multiple SPF records cause authentication failures. If you need to add more senders, edit the existing record.

What is the include: mechanism?

include:domain.com instructs receivers to also check the SPF record of domain.com for authorization. Each include: counts as one DNS lookup toward the 10-lookup limit.
