Second is a ludwigia, best guesses for other would be pogostemon stellaris or limnophilia hippuridoides, limnophilia being more likely. Can you post a whole stem upright shot, a tank shot, and a picture from above?
For sure not ludwigia repens for the plants in question (pics 1/3) but I'm at a loss as to what it truly is. 2 for sure is a ludwigia. Maybe @Silister Trench @-Mak- or @Dolfan can help with a positive ID.
Pretty sure on 1 + 2, but kinda guess on 3. They all appear grown in natural sunlight somewhere because the colors those plants are showing are often not displayed as vividly in the majority of tanks. You'll probably get better identification once the current growth dies back and the plant is grown under your tanks conditions. Someone probably has the same plants, but they're green. 1.) Limnophila Aromatica 2.) Ludwigia Repens 'Rubin' 3.) Laromatica?
