Navigation with the icon to open the page and open the pop-up window

This is my first participation here, so I apologize if I'm not doing it right.

My question is about the use of icons for navigation.

For example:

enter the description of the image here

All items are selectable

1) The first element (My works) opens the pop-up window with a list of all the works

2) The Job icon will open a page.

3) People (User) Icon will open a page.

4) The notification icon will open a pop-up window

5) "Logo" will open a popover

Do you think UX is wrong?
I've seen that this is used in Gmail, StackExchange, Instagram and I'm going to a similar solution.

What do you think about this?
