No.
As everyone has already told you, it isn't ok.
If you were an experienced hobbiest, who needed temporary, emergency accommodation it might be manageable for a short period, but you would understand that it was far from ideal, and be making immediate plans to put it right.
In your situation .... those fish will not be alive if and when you get the new tank built, and that is supposing that the deaths don't put you off building it.
Read the thread, it contains everything you need to know, but you do need to listen.
peace.
