yes very easily what you would do is make an array of GameObjects then setup a GUI with buttons and upon clicking said objects you could then spawn the character according to the button you pressed.

for example in pseudo code

GameObject[7]

   button1Pressed
 {
   //Spawn player at start location
 initiate.GameObject[1] 
 
 GameObject[1].transform = startlocation

 DrawMenu = false;

 
 }
 
 etc

I have character selection screen and it is a scene what i want that selected player should go in my gameplay scene which is a different scene..how can i do it?

I think this tutorial can help you: Link You just have to adapt for when you select a character you send him to you main scene.
