PHP код:

stock GiveWeaponBySkin(playerid) {
    switch(GetPlayerSkin(playerid)) {
        case 0: { //if skin ID 0
            GivePlayerWeapon(playerid,24,100);
            SendClientMessage(playerid,COLOR_RED,"You are skin ID: 0 and you got a deagle!");
        }
        case 1: { //if skin ID 1
            GivePlayerWeapon(playerid,31,100);
            SendClientMessage(playerid,COLOR_RED,"You are skin ID: 1 and you got a M4!");
        }
        //etc. etc. etc.
    }
    return true;
} 


And then OnPlayerSpawn you can add GiveWeaponBySkin.

From what I know there isnt a default function to set more than 3 weapons
