Phalaenopsis Keiki planting help

[Crb0620]

Hi all,

I have a phalaen growing 3 keikis for about 4 months.

2 of the keikis are on the same stem. Both have 1 root.
I do not know how to cut and plant them since they are on the same stem. (The one closer to the soil has a much longer root.)

I also have another keiki on this same orchid but on another stem that has 1 leaf and no root, also growing for 4 months. Can I pot this keiki too even if it has no root?

Thank you for any help!
