Pillar of Autumn:
At the beginning of the level make you're way to the bridge. After talking to Keyes and regaining control of the chief, find the glowing red computer console to find the terminal.

After entering the underground tunnel, proceed like normal, but instead of jumping the gap like normal, find a small side tunnel in the immediate area and you'll find the terminal at the end of it.

Truth and Reconciliation:
After defeating the Zealot on the Bridge, use the red console on the raised platform in the center.

Silent Cartographer
When heading for the Security Building, you'll encounter two hunters in the center of the island. The terminal will be located on the wall of the structure in the center of this area.

Assault on the Control Room:
Toward the end of the level you will come to the Pyramid with the Control Room at the top. You'll notice a long, flat piece of the structure running straight down the middle of it and going into a crevice in the ground below. Go inside this crevice and you'll find a terminal mixed in with a large amount of hidden ammo supplies.

343 Guilty Spark:
After making your way to the Elevator that will allow you to escape the underground facility, you'll find the Terminal above the doorway you came out of. It can be reached by activating the Elevator, than timing it correctly and jumping off onto the platform below (this may take a few attempts, but the elevator can be activated as many times as needed.)

The Library
On the third floor, you'll come to a room with a large circular room (the Index platform will be above it. Go right and use the crouch jump to jump over the barriers and you'll come to a room that looks like the rest of the level, but is disconnected from the regular game. The Terminal will be plain as day before you even reach it.

Two Betrayals:
In the control room at the beginning of the level, walk around the the circular platform and you'll find the terminal directly across from the control console.

After find Keyes absorbed into the Proto- Gravemind, kill the Covenant and Flood that attempt to ambush you, than search the sunken crevices to the side of the raised platform. The terminal will be down inside one of the two.

The Maw:
Play the level like normal until you reach the Cryogenic Storage Bay where Sentinels will be busy fighting the Flood. A glowing Control console on the wall will house you final terminal.


I can confirm that it does NOT have to be in one playthrough. And you don't need to watch the whole thing.
