With the exception of the one sprout with "true" serrated leaves, I'm not going to comment on what is or is not cannabis in your picture.
Prepare separate solo cups for each of the sprouts you would like to keep. Transplant one sprout per cup. You'll figure it out.
I'd wait a few days before transplant. The sprouts are extremely fragile right now. Two, three or even four days is likely not enough for the roots to get too bound together to separate. If you can wait until they all have their first set of serrated leaves, they should be robust enough to hande the transplant. When transplanting, do not pull on the sprouts. You do not want to damage the roots or separate the sprout from the the roots. Place your hand over the top of the cup, invert the cup and gently dislodge the entire volume of soil. You can then - again, gently - break up the soil and separate the sprouts. If any are bound together, you can rinse them with water to try to separate them. You may lose one or two.
Best of luck and let us know how it goes.
