Those appear to simply be "yeast rafts". Basically yeast that is floating on the surface instead of falling to the bottom with the rest of the yeast. You will get used to seeing them in nearly every beer that you make. No harm. If any actually made it into the bottle (unlikely), they will simply sink to the bottom along with the other sediment created by the bottle carbonation.
Now the real difficult waiting begins (at least it was for me on my first couple of batches). Give those bottles around 3 weeks to fully carbonate then put a few into the fridge for a few days before you start drinking them.
Congratulations on your first batch.
