Hello Him, The first one is a correct 1st conditional - If + present perfect, will + infinitive. (Just remember capital 'I') The second one is a grammatically correct 2nd conditional - If + past simple, would + infinitive (capital 'I' again) but I am not sure that the sense is quite correct. Best wishes Bob PS I have a video about conditionals which you may find useful https://youtu.be/rkEiw_H1fp8
