Yes, but they each have a different type of mouthpiece. A trumpet has a metal cup type of mouthpiece, where a saxophone has a plastic mouthpiece that holds a wooden reed.
A trumpet is made out of brass. But why isn't a saxophone a brass instrument? because it uses a reed in order to produce sound while brass instruments use a metallic mouthpiece
begginners should use a C* (Cstar)
Yes. In general, any trumpet mouthpiece can be used on any trumpet.
A saxophone reed is used to put on the mouthpiece and when you blow onto the mouthpiece it causes the reed to vibrate and generate sounds. This is how the sounds are made in a saxophone.
A Reed.
It sounds the same, you just need to push in the mouthpiece into the neck. Just like saying, what would happen if you played a tenor saxophone with an alto saxophone mouthpiece. I have played a tenor before with my alto sax mouthpiece. What I meant to say was to push the mouthpiece in more than you would on the alto saxophone neck. The first time I answered I didn't sign in.

The part of the trumpet you blow into is called a "mouthpiece"
Yes, you'll want to do this.
The ones I've seen do.
The main thing is a sax is a woodwind instrument, played by using a reed, and trumpet is a brass instrument, using a cup shaped mouthpiece with no reed. Also, the trumpet has (normally) 3 valves, where as a sax has 10 or 12 keys (don't know exactly).
