Yes,
Unfortunately, with over 70,000 named ones, it is nearly impossible to identify daylilies, unless they have a really unique characteristic, or you have a list of what you bought and tags were mixed up, some thing like that. Since these were given to you, they could even be someone's seedlings. Add in that daylilies can look different in different soils and climates, and certainly look different taken with different cameras... It is nearly impossible.
I usually advise that people just enjoy them as "NoID" rather than guess.
Welcome to a new addiction! Yep... Daylilies are very addicting!
