Answer 1

You are passing branch with parameter name branches. Change your controller code to:
public function edit(Branch $branch)
{
$branch=Branch::where('id',$branch->id)->first();
return view('branch.edit',['branch'=>$branch]);
}

Answer 2

You are sending 'branches' from your controller and used $branch in your view! Try to change it in your edit() function like:
public function edit(Branch $branch)
{
$branch=Branch::where('id',$branch->id)->first();
return view('branch.edit',['branch' => $branch]);
}
And also, in your index() function change
return view('branch.index', compact('branches'));
To
return view('branch.index', compact(['branches', 'companies', 'dealership']));
Hope this will helps you!

Answer 3

Everything seems to be correct just that you are sending branches instead of branch and when the view looks up for branch it's not available .. that's the error you are getting
