What are these languages among them: **Regular, DCFL, CFL, CSL, REC, RE ?**

$L1=(w_{1}w_{2}: w_{1}\neq w_{2}: |w_{1}|=|w_{2}| )$

$L2=(a^nb^m: m=n^2,n\geqslant 1 )$

$\\L3=(w^n : w\epsilon (a,b)^+,n\geqslant 2)\\ L4=(www^R: w\epsilon (a,b)^+)$

$L5=(wuw^R: w,u \ \epsilon (a,b)^+, |w|\geqslant |u|)$

$L6=(a^nb^ma^{nm}: n\geqslant 1,m\geqslant 1)$
