Sure thing!
2T: 2T is gained by experience in training. A second comma appears in the eyes. The user gains the ability to see illusions, upto C-Rank. Track speed ability and reactions to Taijutsu would be faster than 1T. In addition, the user will be able to anticipate movement by analyzing higher speeds and by reading handseals, anticipate and copy the targets techniques.
3T: Same as 2T, 3T requires more extensive training and experience. The third and final comma appears in the eyes. Once again, track speed ability and reactions to Ninjutsu and Taijutsu are increased manifold. As before, anticipation of movements, analyzing of speeds and handseal reading speeds are increased than 2T. However, using a copied technique, requires extensive knowledge and prior training. Tho, the user can modify the techniques he has copied(in case of Sasuke's Lion Combo). The drawback is that the user cannot copy Kekkai Genkais and Kekkai Totas as well as Summoning Jutsus.
Mangekyo Sharingan: For one to gain the MS, one has to go through extreme mental trauma or near death experience, the same as Sharingan awakening. 1t,2t and 3t have common patterns for each Uchiha, but each Uchiha's Mangekyo differs in it's pattern. As usual, track speeds, ability to read movements, copying handseals speeds' are amplified. Also, Uchihas gain the ability to perform Forbidden Jutsus. Amaterasu, Tsukuyomi, Kotoamatsukami, Kamui, Izanagi, Izanami, Susano'o(increases in size and changes shape as the Uchihas' hate increases and they go into deeper darkness), etc..are some MS techniques, but some of the abilities are exclusive to only certain Uchihas. In short, each Uchiha has a unique ability within them. However, usage of MS, puts immense stress on the eyes of an Uchiha, and overuse leads to hindered vision and finally blindness.
EMS: This can be gained only if there is another Uchiha of the same bloodline who has MS beforehand and has transplanted his eyes on another MS user who's related to him by blood. Known users are only Sasuke and Madara. Same as before, EMS increases tracking speed, analyzing opponent's moves' speed by manifold. Also, unlike MS, the user never loses light in his eyes. Only EMS users gain the ability to control Perfect Susano'o, which is the final stage of it. Also, the user gains the fluidity in movements, as remarked by Madara to Sasuke.
