Can these fishes live together?

Mollies, platies, like to live in groups of 6 or more so you'll probably want to increase the guppies to 6 otherwise, you're fine there. The two kissing gouramis should be fine with that group as well. I would avoid blue gouramis and maybe go with dwarf blue gouramis instead. The tetras would also work well with this group. The only problem I can see with this tocking is the female bettas. There is not enough of them and they generally dont get along platies or gouramis.Anyways hope this helps!
