chlorination of benzene
is possible to do chlorination of benzene with AlCl3 without any special condition?

Depends on how do you define "special condition".
It does not require microwaving, sonication, UV, VIS, IR, etc. lighting, no high-voltage discharge either.
But does require anhydrous reagents because AlCl3 is water sensitive.
The emitted HCl gas can cause unease in a (shared) kitchen environment, so proper venting is also useful.
Might require temperature control, depending on mass of materials used.
Why not consult e.g. Vogel or maybe Org.Syn. for a proper description of the process. Wait! They may not use AlCl3 but FeCl3
instead (or something similar), the quirks are roughly the same.

and is possible to chlorinate toluene to benzyl chloride react it with potassium cyanate and chlorinate benzyl cyanide in pozition 4?

Hmm I have a big bag of FeCl3... I bought it for something else (and only needed a small quantity), but it might be fun to put some groups onto
benzene rings.

But you could easily chlorinate with TCCA! Discussed on the site several times.

You'd need KCN, not KCNO.

If it is in a bag then chances are it is unsuitable for this purpose. Not because of the packaging material but I doubt that anhydrous ferrichloride
would survive in a plastic bag too long. If it is orange colored then it is unsuitable (hydrated). If the color is black and the powder is obviously
dry, then you are lucky.

Adding some degreased steel wool is quite sufficient to form fresh, high-surface area FeCl3 in-situ. It works well with benzene bromination and I'm
sure it would work with chlorination (though I personally loathe working with gaseous chlorine).
