Questions about N_forecast

[potoyeee]

set n_forcast=24, n_lags=24, and add lagged、future regressor.
model predict steps 25 to 48 directly onetime，or predict step 25 then predict26 ?
If it belongs to the latter, predict step 26, its lags=(2,3,......,25)？ use the real value step 25 or predictive step 25？
lagged regressor use the real information in step 25？
thank u！！！
