The first picture depicts a plant that belongs to Subtribe
Oncidiinae. Until it blooms, visible identification on it is nearly impossible.
The second is a
Myrmecophila. This is a segregate genus of
Scomburgkia. Until this one blooms, it will be hard to tell what it truly is. I am guessing it is
Myrmecophila tibicinis because of its size and shape, but it could also be
Myr. brysiana.
Hope this helps somewhat. Just gotta let the plants bloom first!
