The way I read it, one friend conceded that girl 1 liked YOU more, resulting in you getting her number and making plans...
Another friend knew a girl he's now trying to fix you up with, and is sending her your way at the same time the first one will be there.
I would attempt to reschedule with one of them... having them both there at the same time will just not look good. Regardless of what you do, it will look exactly how it is: you're playing games with two girls at once.
