You need to give us more info about your tank. What size is it, how much light
do you have over it, what fish and plants are in it, do you inject CO2, what's
your pH and KH (if you know), etc.

My echinodorus parviflorus leafs after being planted in the aquarium started
to look thiner and after 1 or 2 days holes started to apear in some leafs.

Since you just planted it, it might be just the emersed growth dying off. Or
something in your tank might be eating it.

Also my anubias and Echinodorus have some leafs with brown dots all over it?
Is it the same?

This sounds like it might be algae.
