What size does this make

This kit will yield 51.2 cubic inches of material.

what's the difference between this mold star and the 16 fast?

This version has no color - it is cloudy clear.

Will different silicones stick together when making a mold? I ran out so part of my mold is cured?

You should be fine with using other silicones if you use a silicone release spray when you create your mold. Something like "Smooth-On Universal Mold Release" would be sufficient.

Been wanting to try this. Is there a step by step tutorial before I buy it ?

Yes, if your looking for tutorial videos, go to https://www.smooth-on.com/tutorials/ to learn about the many different mold making techniques.
