Correlation functions of composite operators

I am looking for resources, where there are examples of calculation of correlation functions between composite operators. This is very basic and natural question, but unfortunately, I don’t have any sources..

I am interested in any examples, but if to be concrete, I wanna to understand some basic examples:

1. $lambda phi^4$ theory:
   $$
   langle phi^2(x) phi^2(y)rangle = ?
   $$
   $$
   langle T_{munu}(x) T_{munu}(y)rangle = ?
   $$

2. $mathcal{N}=4$ SYM:
   $$
   langle tr(phi_i phi_j) tr(phi_k phi_l) rangle = ?
   $$
