Bryan, they all look like Phalaenanthe or Spatulata types except the last one, which as you say is Den. lindleyi (aggregatum). I don't grow many den-phals, but I think they appreciate drier (not totally dry) periods once or twice a year. Some sources say this period helps stimulate blooming, I can't really tell with the ones I've grown.

For the lindleyi, reduce water significantly but not entirely throughout most of the winter. Cool temperatures (55-60 or below) are said to be needed for spike formation. I think this one is from deciduous forest regions, so it should like high light in the winter. Hope this helps!

I think 7, 8 and 9 are definately the Phalaenanthe or Spatulata types because of the remains of spikes that I can see. 1-6 probably are as well but I'm not so certain.

I grow the Phal types without much of a rest at all. I do reduce watering, but only in so much as they dry slower in the winter so I water less. If they dry I water, just like in the summer.

Mine seem to be triggered to flower with light and I've had no trouble flowering them without a rest.
