A few challenges will present themselves here. The first chord here F#7b9(no 3) is again best accomplished by keeping the fingers upright on the fingerboard. When you come back to the natural five, you really have to pay attention to the fourth finger and be sure that it doesn't mute the third string. Spend some time working your fretting hand in position first, avoiding overworking of course, and focusing on finger tips and arching of the DIP joints.
