Which are the possibilities that they accept these trades?

The person will expect none of those trades because first of all, you are not giving enough. The 1st trade wont happen because althought their stats are simliar, Putz has SV, but Okajima won't have SV. The 2nd trade he won't do because Willis is sucking this year and I am surpised someone has Conine on their team and Felix is very good 4-tool category pitcher. So if you want those guys, you better give up more to get them. Good luck!
