Can else have more than one statement?

if (control)
	      <statement>
	   
           else if (control)
	      <statement>
	   
           else
	   {
               <statement>
               <statement>
           }

Yes. (But it's really the if - fully brace everything and this becomes obvious.)

Yes.
Generally speaking, any place you can have a single statement, you can use multiple statements enclosed in curly braces { }
