No to Goku, No to Vegeta, No to Jiren. Goku and Vegeta had to fuse so seperate no. Broly is still getting stronger and wiser as well and the zenkai boost after the Broly movie we don't even know how much stronger he is or even how near death affects a saiyan of legend as of right now. Jiren if he takes Broly seriously but given his universes erasure was on the line in the ToP obviously Jirens weakness is his Ego. Broly adaptability is so rapid that he would catch Jiren if he doesn't take him out quick enough.
