Your little yellow one in the group shot reminds me a lot of
Standard Dwarf Bearded Iris (Iris 'Cache of Gold')
The first mini gold one looks like a different iris, from what I can tell, it looks like the beards are solid yellow while the one in the group shout looks like the ends of the beard are white. The clump shot also looks like a paler yellow than the group shot one.
