Is anyone faster than The Flash?

it depends. technically no, but the general answer would be yes.

not really fair to say people like silver sulfer are faster than the flash because the flash is never running at full speed. they talk about it in some of the comics, and its even referenced to in the animated series involving him. theirs a certain speed limit the flash refuses to go pass for fear that he won't be able to slow down."I would live out my whole life in the time it takes a kid to tie his shoe". something about his atoms vibrating so fast he loses himself to the speed forest. anyhow, he's broke it a few times before and it was pretty crazy how fast he was going. and everytime he did it, it was obvious he wasn't trying his hardest. then somehow the justice league saves his ass before he fades out of existence.

so, yes the flash is the fastest man alive, bu,t no because his physical limitations won't allow him to reach such speeds. unlike alien extra terrestrials with the cheat codes to life who break the laws of physics.
