Ironically, Aji Habenaro may be the mildest out of your list.

Aji Habanero Pepper
Capsicum baccatum
A pretty type of Aji, named as such for its appearance and flavor which show resemblance to the famous Habanero peppers. Unlike the Habanero, the Aji Habanero is quite mild, with minimal heat. The flavor has the delicious smoky spiciness that Habanero's are famous for. The bright peppers ripen to an orange-yellow with slight wrinkles.
Aji (Red) #9393 (30 seeds) Tall plants produce very hot 3 to 5-inch orange-red peppers that are generally dried into powder for use in sauces and stews. A Capsicum baccatum type with 30,000 to 50,000 Scoville units. 85 to 90 days.

Aji Lemon Chilli
Aji Lemon Chilli, Capsicum Baccatum, is originally from Ecuador or Peru. Also known under various other names: Aji Limon, Lemon Drop or Hot Lemon Chilli. The plant grows to about 1 meter in a pot and would grow bigger, if you plant it in the ground. The fruits ripen from green to a pure lemon yellow. The pods are small and measures 5 – 7 cm long and if you dried this chilli, it becomes wrinkled and tapered. The fruits have a strong citrus overtone and goes really well with seafood, stir fries or Thai food to give that citrus hint of flavour.
Aji Amarillo
Aji Amarillo, a Capsicum Baccatum from Peru. This is the most widely chilli/pepper used in the Peruvian cuisine.
The chilli plant is tall and needs staking as the pods weigh the branches down once it pods up. All our Aji Amarillo chilli plants are in pots and grow to over 1.5m tall. A great producer of around 15 cm long and about 2.5cm wide pods. The pods start odd a green and go to an amazing orange colour.
Would be great as pickled, as a pasta, in a salad or in any cooking.
Overall an awesome looking plant with a lot of big, brightly coloured pods. The Aji Amarillo will look great in any garden and it is a great all rounder, heat is decent, great flavour and it’s a great producer.
Flavour Wise: Nice and crunchy really really sweet capsicum like flavour, like a snow pea. Thick and meaty pods, that seem to take forever to chew. The flavour stays as its not overly hot, flavour stays for ages and love it. The sweetest pod we ever tried.
Heat Wise: Heat hits pretty quick and has a nice solid burn to it. Upper mid heat.
