Create an Excel document with a macro for displaying a list of random values

Dear Freelancers, I would need a macro for excel with 2 buttons on the worksheet, one that generates a list of 500 random and unique combination of numbers, the second button adds 2 other random numbers besides each row. (please see screenshot attached as an exemple) I would also need a precise description how to use the macro in Excel you provide me, where to past it so that it works (I am a beginer in Excel). Or you should send me an excel doc containing the macro so that I just click on the buttons. : -)) 1) Clicking on First button (called Nombres) would do this: Create a list of 500 rows. Description of the list: First Row: Column A, B, C, D, E contains a random number between 1 and 50. Each number has to be different in each column (if num in B is same than in A, choose a new number, in C if same than A or B, then choose another number etc.) Then set the numbers in that row from the smallest until the biggest, then finally the numbers can appear in that row. Next Row: Same as above, but needs to have a serie of numbers with at least one number having a different value than in all the rows above, if it is different that serie of numbers can appear also (i don't want duplication of lotto combinations in the list), if the serie of number in that row is the same than one of the rows above, then create a new random serie of numbert and if at lease one of the number is different, then that row can be accepted / printed Then the macro can create next row until the 500th row. 2) Clicking on Second button (called Étoiles) would do this: Add 2 random numbers (in RED color) at the end of the serie in each row randomly between 1 and No duplication test is needed for that second part, it should be random..., but it does not matter if there is a repetition within those numbers. Then if I click on first button a get a new list again of 500 rows, and if on 2nd button, then a new list again besides all the rows. I would need it within some hours if possible. Kind Regards,
