Does anyone how many samples need to be taken if I want to test structural equation modeling for the model here? ?

Hi! Everyone!. As stated in the question above, may I know how many samples should I need to take if I need to conduct this model? basically I want to prove the effect between the independent variable (variable 1) with the rest of the variables ( variable 2 to variable 5) as dependent variables in this model.
