Can one order contain multiple different files with different quantities each?

A single order line is built around one product setup and quantity, so mixing several different files each at its own quantity is not a standard self serve option. The best path depends on what you are printing.

• Same product, one design: upload one print ready file for the full quantity.
• Same product, a few designs split evenly: ask support about a multi design or ganged run.
• Different designs at different quantities: usually cleaner as separate order lines.
• Large or complex mixes: contact 4OVER4 support so they can map the files to the right setup.

Reaching out with your file list up front lets the team confirm whether it fits in one order or needs to be split.
