Silicone is more heat resistant than "rubber" or hard plastic vacuum hoses, and costs more, which is why factory doesn't use it

Local auto parts stores should sell different sizes by the foot, you will also need some 90deg fittings of correct size on some engines/hoses, you don't want to bend a hose that far

Vacuum is negative pressure so PULLS connections together, which is why you don't see clamps on the hoses, but they do need to be the correct size to have a good friction hold and seal, on the port and device they connect to
