Please could someone identify these two plants?

Had them for a while and they’re nice, anybody know what they are?

no idea about the pic on the left but the plant on the right is Ambulia and it's looking a bit shabby.

If you don't fertilise the plants, then get some liquid plant fertiliser like Sera Florena and add that once a week.

First I want to say is a type of hygrophila, perhaps hygrophila augustifolia

I’ll add some liquids ferts, I have never used them before and haven’t had many issues until recently.

A decent liquid aquarium plant fertiliser will make a huge difference to plants. It takes a few doses but once the plants have repaired the damage, they tend to take off and grow really well.

A good way to monitor plant growth is to photograph the tank each week and compare pictures.

I can't tell from the photo...

left pic I'd suggest Rotala Indica?

Pretty sure the one on the left is needle leaf repens (Ludwigia arcuata). Definitely not Rotala indica...unless it's a different form from what I've kept.
