These spiders sit in the wall at night and dissappear in the morning, which spider is this? Sorry for the bad photo, I am scared of them. England

Also a silly question but there are plenty of these spiders on the same wall, like 20 of them, and they all sit in the holes. Do they have their allocated hole, or do they just sit in a random one?
