I want to know how much i should save up so i can buy the things i need and to pay off the first months rent and security which the rent is 800. im just talking about to be able to move in for the first month. not talking about my bills like car insurance. just things i need if i were to buy what i need now. i made a list and its about 2500$ i am going to save $5000 is that fine?

Ya, it's absolutely fine and you have made very perfect list. I must say just go for it.
