Is there any way to get an emergency home xbox switch

No. Also, sharing your account information in order to game share violates the code of conduct. So you and your friends are putting yourselves at risk for being banned.

I Have Received The Emergency Home Switch From Help And I Really Need This Switch To Get Him Into Xbox

Home Xbox is not designed to be moved around frequently (if it's moved at all). Users can still play all their games and access all their content by signing into an Xbox One that is connected to the Internet.

A user is granted five (5) chances to move their Home Xbox setting in a 12-month period. One emergency switch is available through Xbox Assist on the user's console. After that emergency use is utilized, the user must wait until the oldest move drops off
their account; the date is shown on the user's console in the My Home Xbox section of Settings.

Sorry you have already used up the 5 switches and the emergency switch. You will not be grated any more switches until the date stated on the console!

basically, my girlfriend has used all of her home xbox switches without realising but when it comes to trying to get a final extra one theres no option to but shes never done it before and her home xbox is at her old mates house who she fell out with is there any way without waitin like weeks that she can get another one?

If its not giving the option for the survey (to get an extra switch) then there is no other way other than waiting for more switches as they become available.

Support doesnt even have the option to give extra switches anymorem
