pawn Код:

new Text:g_Textdraw;
#define TEAM_BLUE 1

public OnPlayerSpawn(playerid) {
    new
        g_Blue
    ;
    for(new i = 0, j = GetMaxPlayers(); i < j; i++) {
        if(GetPlayerTeam(i) == TEAM_BLUE) {
            g_Blue ++;
        }
    }
    new TD_String[20];
    format(TD_String, sizeof TD_String, "Blue: %d", g_Blue);
    TextDrawSetString(g_Textdraw, TD_String);
}

or this?

and if u change team of a player with a command create a function with this code.. exemple:

pawn Код:

stock UpdateTD() {
    new
        g_Blue
    ;
    for(new i = 0, j = GetMaxPlayers(); i < j; i++) {
        if(GetPlayerTeam(i) == TEAM_BLUE) {
            g_Blue ++;
        }
    }
    new TD_String[20];
    format(TD_String, sizeof TD_String, "Blue: %d", g_Blue);
    TextDrawSetString(g_Textdraw, TD_String);
}

in OnPlayerSpawn: UpdateTD();

in ur function UpdateTD();

remember to use SetPlayerTeam for teams..
