Navigation with icon to open page and open popover top

This is my first participation here so apologies if I am not doing this right.

My question is about about using icons for navigation.

For example:

All items are clickable

1) The first item (My Works) open popover with list all works

2) The Job(Briefcase) icon will open a page

3) People(User) Icon will open a page

4) Notification icon will open a popover

5) "Logo" will open a popover

Do you think bad UX? I have seen this being used in Gmail, StackExchange, Instagram and I am heading towards a similar solution.

What do you think about this?
