with 9 v dc batt.

need to know what resistors to add where & also code(or choices) of transistor that i can use

need a reliable circuit, with minimum heat dissipation

This looks like a homwework or coursework question. You appear to be asking others to do your homework for you. You will learn nothing from that approach. If you are to learn stuff you need to do it. If you do not know how to do it then you need to find out how to do it. Before you ask others for help you need to show that you have at least tried to find suitable sources of information. So, start here: https://electronicsclub.info/transistorcircuits.htm and then search for other sites with similar (basic) information. Then I suggest you learn to use the simulation tools in EasyEDA to simulate your circuit before you try to build it on a strip board. You can learn about that in (3) of: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f

You also need to specify your circuit better. For example, 1. how and to what voltage(s) are the switches connected? 2. What LED are you trying to drive and therefore how much current do you need to drive it? See (2) in: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f
