But you code isn't correct.

pawn Код:

public OnPlayerSpawn(playerid)
{
    if(IsPlayerNPC(playerid)) return 1;
    if(IsPlayerNPC(playerid)) //Checks if the player that just spawned is an NPC.
    {
        new npcname[MAX_PLAYER_NAME];
        GetPlayerName(playerid, npcname, sizeof(npcname)); //Getting the NPC's name.
        if(!strcmp(npcname, "Soldier_1", true)) //Checking if the NPC's name is MyFirstNPC
        {
            SetPlayerSkin(playerid, 287);
        }
        if(!strcmp(npcname, "Soldier_2", true)) //Checking if the NPC's name is MyFirstNPC
        {
            SetPlayerSkin(playerid, 287);
        }
        if(!strcmp(npcname, "Soldier_3", true)) //Checking if the NPC's name is MyFirstNPC
        {
            SetPlayerSkin(playerid, 287);
        }
        if(!strcmp(npcname, "Soldier_4", true)) //Checking if the NPC's name is MyFirstNPC
        {
            SetPlayerSkin(playerid, 287);
        }
        return 1;
    }
    return 1;
}

It doesn't need to have two

    //For normal players goes here!

}

Also, check again if the 4th NPC's file (.rec) is on the recordings folder and the .pwn in the npcmodes
