Drip Edges, Corners, and different felts?

Hi All, Just had my roof replaced in Dallas, Texas. My roofer didn’t replace my old drip edge even though it was in our contract and insurance is paying for it. Some of the drip edge was taken out and put back on during install of new roof. Wondering if it is okay that it is not laying completely flat? Should it be replaced or can it be fixed? Noticed the corners look off to me as well, but I am by no means an expert. Are the corners/edges right and have enough overhang?

Also, during install of the new roof- they laid 3 different brands of synthetic felt I believe. Is that normal? (TriBuilt, Rhino on front and Infinite on back of house)
