I have some queries about Juma prayer,
1. Can Juma prayer be conducted in each and every mosque?
2. Can it be offered in a mosque where five daily prayers are not offer, for instance a mosque in office.
3. What is limit of minimum persons to get together to offer Juma prayer?
Answer to questions 1 and 2:- Yes
I'm not too sure about number 3 but i think including the imam its three people
Inshallah someone more knowlegable will confirm or give you the right answers
