This post is in regard to the North Indian Armies from Post 200 CE, covering mostly Gupta, Pushyabhuti and Pratiharas.
Firstly, the Guptas (300-500 CE) need to have at least 6 Noble Lancers and around 8 Indian Lancers, and maybe 1 Chariots ( since these were only ceremonial by this period).
Similalry the Post Gupta North Indian Armies (600-800 CE armies) also need to have a very strong Cavalry contingent. They should have at least 8 Indian Lancers and 10 Indian Light Horse.
Reason being that during the Gupta and the Pushyabhuti empires, the supply of good warhorses from areas such as Aratta, Sindhu, Kamboja and Tangana were secured. We get an estimate of Emperor Harsha's army strength, both when he was a regional king, and after his elavation as the Emperor of North India. Chinese Traveller Hieun Tsang who visited Harsha's court, states that when Harsha was just the King of Sthaneswara, he had some 20,000 Cavalry, 5000 Elephants (Elephant figure seems exaggerated) and some 50,000 Infantry, once he conquered North India, he had come 100,000 Cavalry, and 60,000 Elephants (once again the elephant figure seems to be an exaggeration). It is to be noted that Harsha did not incorporate beyond the Indo Gangetic heartland.
Coming to the Infantry, armored infantry had become the norm from this period onwards. Banabhatta, Harsha's court poet, gives us a description of Harsha's army camp when he first had gained the audience of the Emperor. Most soldiers wore a jacket (Kancuka) and a helmet (Khola), meanwhile the nobility wore Kavaca armor, whether this Kavaca was a coat of mail or some other iron armor such as scale, it is unclear though.

The above links are of an excellent site that has freely available excerpts from the translations of important texts such as Harsacarita, Arthashastra, Nitisara etc, that give us the description of arms and armor, as well as the military organization of the time.
Coming to the Rajput list (650 to 1050 CE), this would be representing the Pratihara Empire, I have already stated that the Arab and native accounts give us a fairly full picture of this empire. Hudud Al Alam (late 10th century) tell us that this empire had some 800 Elephants and 150,000 Cavalry, while Suleiman and Al Masudi, both of whom visited the empire in its heyday (mid 9th and early 10th century) give us pretty exaggerated figures, though the note that the empire had 4 great armies for the 4 directions, and that their armies were known to have large number of camels and horses, making it the finest cavalry force in India.
This army should have at least 6 Armoured Indian Lancers, apart from the Superior Indian Lancers, since by this time mail seems to have become common, especially in North India. Not to mention that unlike the Rajput Army from 1050 to 1350, this period saw a unified empire, not just regional states. As such I suggest at least 6 Armoured Indian Lancers, along with 10 Superior Indian Lancers, to be added.
The period from 200 CE to 1000 CE was the Age of Great Empires in North India, with the Guptas, Aulikaras, Maukharis, Pushyabhutis, Ayuddhas, Karkotas and finally the Pratiharas, as such this period should have very strong armies.
Lastly, this is probably a good example of the armor that the Elite North Indian Cavalrymen would wear between 200 CE to 700 CE, this is a coin of Emperor Samudragupta (d. 375 CE)
