Only iOS devices have Lightning sockets; MacBook Pros have Thunderbolt. If it's a Thunderbolt 3 (USB-C type connector), then yes, it acts as a USB port so you could use a USB-C to USB-A adapter or cable. If it's an older Thunderbolt 2 port, you would need a Thunderbolt to USB-A adapter.
You can always use a USB hub for the other devices you have connected - we recommend connecting the mixer directly whenever possible.
