Yes, the grammar in the sentence "The attached invoices have been confirmed" is correct.

Yes, the sentence is correct. It effectively conveys that the agenda for the Advanced Development meeting in September is included and ready for review.
It would be grammatically correct to say: Please find the attached.... it does not make much sense to write both kindly and please since both almost mean the same.
Please find attached my repairing offer confirmation.
It should be "Please find attached my husband's insurance card".
Please find attached the leave schedule of all staff for the holiday

No, "will be had" is not a correct grammar. The correct grammar would be "will have."
The grammar in your sentence is mostly correct, but there are minor adjustments needed for clarity and punctuation. It should read: "Please find attached a Preliminary Invoice for your reference. Be aware that this is not a final invoice." Removing "an" before "attached" improves the flow, and there should be no space before the period after "invoice."
