I think one should not trust that chart on Anemone compatibility. Anemone compatibility is not black and white. Anemone see to be tolerating each other well for a while then start to sting, then OK again. I have no idea why.
For sure OP have a BTA and a Condylactis. I am not certain the species of the third anemone. Need clearer picture. Host anemone often just move when they are sting by coral or another anemone.
I think the shunk anemone of the OP is sick. He may or may not recover. Healthy anemone rarely completely deflated like that. They do ball up sometime in the evening. This is not a huge problem, but deflating is. When the anemone have abnormal postures, more and more, you need to get him out for treatment. If he just did it once or twice and recovered, then observation ready to take him out for treatment is OK.
If that anemone deflates again, and if he is in my tank, he would go into a HT.
