also is it ok to expose my venus flytrap at the sun whole day and by night put them near my window with ordinary fluorescent bulbs outide? or do i have to limit light exposure ? Im would be at zone 14 or 15(average annual temperature of 25.5°C).

in general, plants need a time without light also. if you have the natural sun exposure, that should be sufficient for the plants.

in fact, once your plants get acclimated to being outdoors, you could leave them outside.

its been 2 days and traps are still closed. lost 2 more traps. :( got 7 left

Give it more time. RELAX.
