You can't tap more creatures to convoke Knight-Errant of Eos than is necessary to pay for the spell. In most cases, this means five creatures. However, if there are any additional costs to cast Knight-Errant of Eos, you may use convoke to pay those additional costs as well.

If a creature you control has a mana ability with in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
