How to analyze the enemy HP
When you launch Final Fantasy VII Remake for the first time and read the opening chapters for the first time, you will not have access to the ability to scan your enemy for his HP. Instead, this ability only happens in Chapter 3.
When you finally get a chance to start exploring the slums in Sector 7, you'll eventually come across a character named Chadley. This character plays an important role in the game by presenting the Battle Intel sidequests. For starters, it will give you a special type of Materia, the Assess Materia, which is going to be very important here.
After obtaining the Materia rating, attach it to the weapon or armor of any of your characters that you will currently have in battle. At this point, enter the battle and get your ATB gauge at least half full. Once you've got it at least half full, you want to press X to access the commands menu, select abilities, and scroll down to rate.
Using Evaluate will give you a breakdown of details about the enemy you've targeted with the ability. This will tell you not only enemy information like weaknesses, but most importantly the enemy's HP. This will show the total HP and what the current HP is as well.
If you upgrade the assessment material to level two, you will also be able to target all enemies on the screen at the same time. This means that you can see the details on each of them and scroll between them with the D-Pad.
If you've used Evaluate on an enemy before, you can just press the Touchpad in the future while in a battle with the enemy as well to get these details.
