I'll start you off by looking at the blank for D.

The completion time for D can be worked out by looking at when B finishes (5 hours minimum) which is also the EST for D. Then have a look at the EST for H (9 hours). This is the earliest that H can start 'cos it cannot commence until D is finished and so D must take 4 hours to complete.

For LST for A, work out the float for A

If you are still stuck, post again.
