Yes, all are correct.
The only other thing is whether your teacher wants all the abbreviations spelled out. But that wasn't part of your directions, right?
1. Bob is 4 cm shorter than Emily.
2. Mr. Pitt is 16 kg heavier than
Emily.
3. Emily is 1 year younger than Bob.
4. Bob weighs 4kg more than Emily.
Are the expressions correct? I think they all are.
