Mystery plant propagation update: Anyone recognise what plant this could be?

I received 3 random leaf cuttings over a year ago now, i had never propped from just leaves before so I wasnt holding my breath that anything would happen with them and asked you lovely lot for any advice you had on leaf propping. All three rooted, only two survived and New growth appeared. Anyway we are over a year on now and this is how they are doing . I love them dearly but I have no idea what they are, I wanted to post an update and see if anyone had any ideas? 😊 (last two pics are recent).
