You've posted essentially the identical request across the UA and US forums and possibly beyond, with no indication you've taken any steps on your own, either by searching FT or by calling either airline.

Suggestions and some info:

1. Please do searches first. There are tons of threads here on how to find award availability.
2. Please make some attempt to find out what the airlines have available.
3. There's no combination "Star Alliance Award Coordination Desk". You'll have to take your chances with each airline.
4. Using the ANA airlines award site. Search, there's plenty of threads about it - basically you have to sign up as an ANA member and then you can search without actually having ANA miles. ANA currently doesn't show Swiss flights. It does have ANA, LH, UA, AC, US, and several others.
5. If ANA shows it available, it does not mean that UA will allow it. Again, search or browse the UA board - many threads about UA not allowing, or not even seeing, availability that ANA and other *A airlines have for awards.
6. If ANA shows it available, it does not mean that US will allow it either. Right now US is having major problems with *A awards.
7. Getting 4 people on the same flights in F is perhaps a bit overly optimistic.
