Is it appropriate for a daughter-in-law to let her colleagues live at home behind her husband's back?

In fact, it is very inappropriate to do so, which brings inconvenience to yourself and others. Even your colleagues will find it inconvenient, because after all, you have a family and a male host at home, and you have not discussed it with your husband, which makes people feel embarrassed. So try not to let others live in their own homes. If you can afford it, you can rent him a house or book him a hotel, so that everyone can.
