This is a very interesting question, and in this context would depend on how you define the word "loyalist." Most major Indian freedom fighters were Anglophiles to say the least, and loyal to the empire.

Gandhi was an anglophile, Nehru was an anglophile, to some extent, even Patel was an anglophile. Gandhi went on record (in South Africa) saying that the British government system was the best suited, for SA, as well as India. It wasn't until the late 1920s and early '30s that the Congress moved towards the demand of complete Independence. Until then, all they demanded was dominion status. Even then, for independent India, the last British viceroy (Lord Mountbatten) was asked to be the first Governor General of Independent India, the government even joined the Commonwealth.

In fact, in the Indian context, a more suitable approach (in terms of Indian freedom fighters) would be people who were against the British empire. Notable names here would be Bal Gangadhar Tilak, Bipin Chandra Pal, Lala Lajpat Rai, and Subhash Chandra Bose.
