Death Star Plan 1 (Jar Jar): In the hidden room above the drop off. Jump up to enter it.

Death Star Plan 3: Once you reach the bottom. Drop to where you spawned here in the previous Utapau level. It's sitting in here.
Death Star Plan 4 (Jar Jar): Drop down at the furthest point you can. Follow the path around the bottom and jump onto the platform. Follow it around to find the Plan.
Death Star Plan 5: It's sitting on the path as you make your way to the exit. Kinda hard to miss.
