Hi Antti,
I'm not familiar with most of those orchids, but I have the Angraecum Sesquipedale I bought young last August. It doesn't require high light, so you should be all set. I'm experimenting with mine and it seems to be doing well, although too young to blossom yet. I mist it early every morning and make sure it's dry by late afternoon. I water it very well, then let it dry out completely before rewatering. Maybe once a week if that. Mine is on a table near a window, but not really getting strong light. Hope that helped. I'm kind of green at growing the more difficult orchids.....but this one seems quite happy. I couldn't resist either!
