I think you mean the starred ones are asymmetrical; each has four different substituents.

@mjc123 yes I meant asymmetrical, but how can I see the four substituents if they are all connected?

Generally you just extrapolate as long as you need to. 1-2 positions is usually enough.
So, for example, consider the top right starred carbon. The four substituents are:

1. -H

2. -CH2-O-.

3. -CH(-O...)-CH...

4. -CH(-CH...)-CH2...

They are all different.

Please don't change your original post after it has been replied to, otherwise the replies make no sense. Make corrections in another post if necessary. Don't feel pressured to hide your mistakes - they're nothing to be ashamed of in a learner.
