@Plumeriaolives 
your cuttings look healthy.
You definitely have an inflo! I have let a multi-tip cutting keep its inflo instead of cut it and it did fine and the blooms look healthy.
Bottom heat is important when rooting plumeria cuttings. I do have a habit of letting my cuttings not totally dry out. Moist but not wet but I do allow it to dry but not too dry.
