I have read that "I2C standards does not allow to connect slaves with same address on same master.". Also each chip vendor assigns an address for I2C communication.

Question 1- Would all ADS7830 have same I2C address (I think it is 0x4B) Question 2 - If all ADS7830 have same I2C address, does this mean I can't use more than one in the same circuit?

The ADS7380 has, according to the data sheet 2 address pins. That means you can connect up to 4 of them to the same I2C bus. If you need more, you can either use multiple I2C busses (the Raspberry Pi 4 has up to 6 of them) or use I2C multiplexers.

If you use breakout boards, they usually use pull-downs on the address pins, but you can normally still change them, either by soldering a bridge on the board or by using the A0 and A1 pins, if they're wired out.
