Welcome to the forum and here is some help.
Top Left :- Odontocidium Wildcat(Odcdm)
Top right :- looks like a Miltonidium (Mtdm)
Middle :- Miltassia
Bottom :- looks very much like Oncidium Sharry Baby but I think that it is an Oncidium with Miltonia warscewiczii as a parent ,I can not at this time remember the name.
I will let others here give advice on window culture of these plants,
