at the same time? That was my question
At the same time? Do you understand how an interfaith chapel works? There are regularly scheduled services for all faiths, and in-between the chapel is open to anyone to pray at their leisure. I (a Catholic) have been in the chapel praying next to a Jew on several occasions.
Services, even when scheduled for a particular faith, are open to anyone. So, if you want to attend the Baptist service, the Catholic Mass, the Hasidic Jew or the Muslim services, you'd be welcomed.
