I think the first is a lobelia but im not sure, grow alone in potting soil with HM I dont put that plant in the soil, it grow from the soil, I put it in the aquarium for fun and then it is growing

Is the plant a rosette plant, perhaps an Echinodorus species of some sort? Hard to tell form the pics.

acuaristico

well the plant continues growing!. maybe a echino? but seems very soft leaves, yea its a rosette plant. More pics soon!

I move it close to the rock because is getting big.

Well I think that the plant is frogbit or some like that.

I think the round-leaved plant is something from the family Pontederiaceae. Maybe one of the broad-leaved Heteranthera species. ID may be possible when the plant is full-grown (emersed or with floating leaves) and flowering.
@acuaristico: Where did the potting soil come from?
