You can mix and match a variety of snacks and sell them in a box, and register a trademark. However, it should be noted that the original packaging of snacks should not be destroyed or changed, otherwise it will constitute reverse trademark counterfeiting and infringe on the trademark use right of snack manufacturers.

If you use cartoon patterns, you must obtain the consent of the pattern author or the agency, and pay the fee. Otherwise, the copyright of others is infringed.

Others imitate you and sell a variety of snacks in a box. This behavior is not illegal and does not constitute unfair competition. Think about it, there are many manufacturers of instant noodles with the same taste, and the act of producing a convenient denomination between these manufacturers is not infringing, is it?
