I am working on a project in which I have to connect multiple (5) load cells or any other weight measuring sensor with accuracy ~50gms with a single Arduino board?
Is there some sort of hub available or any other work-around to connect many sensors with one Arduino?

No you just wire them up to the analogue inputs if that provides enough sensitivity. If not you have to amplify the signal first.
It depends on the kind of load cells you're using. Do they output analogous voltages or digital signals?
Assuming that you want to connect modules with digital signals, what interface (I2C, SPI...), what cable length?
I2C modules usually have limited address range, disallowing the use of 5 modules on the bus.
SPI is more flexible, WRT cable length and number of connected modules.
Post a link to the datasheet for your load cells.

Yes you are good at posting. Especially cross posting. Do not do it here, it makes people cross.
