At this size, I think these are all asiatics. Usually oriental lilies, like Stargazers, come up a few weeks after asiatics.

My Stargazers sprouted first and are now about a foot and a half! Well larger than my asiatics. None of those look like the Stargazers that I have...

Maybe wait until they bud and then you can remove the ones you do not want. Stargazers have MONSTER buds that stick straight up. At least mine do...

You do not have to wait for the buds. It is impossible to confuse leaves of Orientals with leaves of any Asiatic. Apart from that, Orientals and Asiatics have different requirements concerning pH. Orientals prefer acid soil, while Asiatics do not like too acid.

This is a picture of my Stargazer lilies sprouting. I would say from the two pictures that was supplied that the 2nd picture is of the Stargazers.
