Corrected entry: After flying with the movie's hero, Lois comes up with the name "Superman". But what else is the letter "S" for on our hero's outfit? This name was already given to our hero OR the suit or S sign should have been designed after Lois thought of the name.

Correction: This is explained in the comics. Superman's "S" is the symbol of the House of El. Lois thought it was an "S" and came up with Superman as a result.

Lois does not notice nor mention the S on his chest (which, as you pointed out, is not an S at all). After Superman drops her off, she's talking out loud to herself and says "what a super man", which then gives her the idea to call him "Superman."
