In the Battle of the Bastards how can Jon know who his men are?

I can't find any kind of identifier or sigel on the individual men.

Would it be perfect if I finish Drogon or does it need something more?

One thing the adaptations have over the books? Hair diversity

If Jon didn't do what he did in this moment could Daenerys have been as popular and known in the history of the 7 kingdoms as Aegon the Conquer? Assuming her line last 100-120 years down the line
