I have been going through an old Bhopal collection, bought on E-bay about 10 years ago, assimilating it into my Indian States album, I have identified about 35 stamps to my satisfaction, but these few I question:

Tentatively, I identified these two as Scott # 10, 1/2 anna red, perforated, from 1879-80. Anytime I find the rarer stamps I am skeptical of my identification of them, but to find 2 in one collection seems unlikely at best. However, both of them are torn and repaired with old stamp hinges, so maybe this identification is believable.

These 3 are on laid paper and seem to be Scott #22, the 1/2 anna in black from 1884, imperforate. All 3 have subtle design differences. The first one has a dash under the "JA". The other two do not, they look similar to each other, but the middle one is taller and narrower than the last one. I know that each stamp in the sheet was hand-drawn on the lithograph stone, so there is a great deal of variation, and every stamp in a sheet is different, but are these all from the same sheet? ...and have the same catalog number?

I do not have a Stanley Gibbons catalog, which would probably be very helpful here. These all seem to be Scott # 25. They are on wove paper and seem to be the 1/4 anna in grayish green, imperforate, from 1886. There are at least 2 shades here. Each of them has a backward "N" in NAWAB. Are these all Scott 25 or something else. Are any of these (or the previous stamps) later reprints?
Please help me confirm the identities of these if you can. Thanks!
