1. I brought a beautiful hardy water Lilly (Nymphaea 'Marliacea
Albida') that we're blooming in the shop and had another bloom on the
way, I put the plant in the water (60cm deep-like in the shop), the
flower bloomed for 3 days and then never opened again and went back
into the water, the other closed bloom, that were on the way, got
detached from the mother plant after a few days. is it natural ?

Yes, lilies only bloom for 3 days, maybe 4 if the weather is cool. At which
time one should pinch it off at the base.

adjusting to the new environment ? Will it bloom again this year?

As far as the other buds, I assume they got damaged in transplanting, but
it will get more buds. Just keep the old ones pinched off and feed the
plant with lily tabs or equivalent.

2. the water looked clear and beautiful for a week and then became
green-brown including the waterfall stones, the fish still look happy
and energetic and the plants green and fresh, will the water become
clear again after the pond will balance it-self

Yes. Testing for ammonia, nitrite, pH & KH would give me more of a clue how
far you are into the balance act. Also, DO NOT START OVER with new water.
It is okay to do frequent partial water changes. ~ jan
