To disable commands just use the Dming variable. Example:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if(!strcmp(cmdtext, "/SomeCommand", true))
    {
        if(Dming[playerid] == 1) // if in dm
            return SendClientMessage(playerid, -1, "This command is disabled in dms!"); // return error
            
        // Not in dm, do your command.
        return 1;
    }
    return 0;
}

For many spawns you should use Random which generates a pseudo-random number. Example:

pawn Код:

new randSpawn = random(4); // 4 is the highest possible random number. So this is suposed to choose between 4 spawns ('numbers') randomally
// The above code will generate a random number of four numbers (Starting from 0 not 1)
switch(randSpawn)
{
    case 0: // if randSpawn equals to 0 (First Spawn?)
    {
        // Your first spawn place code
    }
    case 1: // if randSpawn equals to 0 (Second Spawn?)
    {
        // Your second spawn place code
    }
    case 2: // if randSpawn equals to 0 (Third Spawn?)
    {
        // Your third spawn place code
    }
    case 3: // if randSpawn equals to 0 (Forth Spawn?)
    {
        // Your forth spawn place code
    }
}
