Pics are good enough to be able to answer your question. The larger swords in the back corners will grow close to the surface in time, and may send out inflorescences with daughter plants. In my experience, this usually takes severalmonths, but it varies on the plant (how it was propagated), water, light, and nutrients especially. Expect some of the existing leaves to yellow and die; as long as new growth appears from the centre of the crown, the plant is fine, and you shuld see this new growth (leaves) within a few weeks.
The front plants seem to be a pygmy chain sword or perhaps a Sagittaria. In either case, runners will appear (there already are, these may have come with the plants?) again depending upon afore-mentioned factors. If those azre swords, the leaves on the parent plant seem to be the emersed form and they may also gradyually yellow; I think I see a couple already. Not an issue, perfectly natural.
I didn't see any reference in this thread to fertilizers; are you using any, and if yes, which and how often? And is the substrate enriched?
