Please help to identify the disease

[Witcherty]

Dear all, please help on the below if you can have any ideas! My friend has mini orchids collection and keeping them in a terrarium. all was good and great for several years already, but now she has following simptoms on the plants. she did the pic of some plants so I put links here. Plants are worser as she says almost every day and we have problems in identifying the threat. if anyone can help with solution or reason of the problem please help. apparently she has almost all plants in terraiums infected.
