Arduino MKR wifi 1010 Project

I have made a lot of progress on my project to build the Arduino mkr wifi 1010 on a PCB, and directly connect sensors to the SAMD21G IC.

I wanted all the sensors to run and collect data simultaneously.

I was curious about the SDA and SCL I2C pins, was it possible to have all the devices running on just these two pins?

Off the bat, the Arduino has the NINA Bluetooth module, and Battery management system connected to it.

I would be adding the Heart rate sensor and thoracic impedance sensor which also need SDA and SCL connections.

So my main question would be, Is it possible to have all these ICs connected to the same pin 13 and pin 14 I2C bus from the ATSAMD21G and for them to run continuously or simultaneously without any issue?

If it is possible, would I need to make sure my code and software firmware running is accurate?

If it's not possible, do I use other serial comm connections and configure the pins for I2C capabilities?

I will provide some pictures. Any tips and Advice would be greatly appreciated. Fairly new to this.

I2C is defined to handle up to 127 devices. In reality the pullup needed will be critical.
