Here are some simple, Jain-friendly girl names that have M and T (either starting with M/T or containing both letters):

Names starting with M (having T or commonly used in Jain families):

1. Maitri – friendship, loving-kindness
2. Mantra – sacred chant
3. Mukti – liberation, moksha
4. Mrunmayi / Mridumati – gentle, soft‑natured
5. Mahati – great, noble

Names starting with T (popular in Jain families, some with M sound/meaning close to maitri-type virtues):

1. Trisha / Trusha – desire for higher life / thirst for knowledge
2. Tanmayi – absorbed in, deeply focused
3. Tripti – contentment, satisfaction
4. Tejal / Tejalata – brightness, radiance
5. Triveni – holy confluence (three virtues/paths)

Names that clearly have both M and T in the spelling:

1. Maitri – (M + T + R + I)
2. Amita / Amitaay – infinite, without limit
3. Smita – smiling, pleasant
4. Samita – peaceful, collected
5. Tamira / Tamita – one who is pure (regional usage)

If you tell me:

• whether you prefer it to start with M or T, and
• which language style you like (very traditional / modern-sounding),

I can refine this to a shorter, more specific list.
