At first,can you change the i2c address on your max30102 module? ( Es. Soldering two pads ) If you can , the lib can be adjusted/ modified as class and using multiple instances that can be achieved.

Although it's possible to put multiple devices on the I2C bus, as @sergiocntr suggests, I am afraid the Arduino Uno CPU is not powerful enough to handle two sensors at once. It can barely handle a single one, as it is.
