As hamsters get older, they may grow quite obese, or rather skinny and scrawny. Providing the are healthy, eat and drik properly, there is no need for concern. I would observe them at eating time, to see if the thinner one may be prevented from feeding. An answer to this would be a second bowl. You may try to feed her manually for a while. Just small amount... If you have a pair of reasonably accurate kitchen scales, weigh and record her weight, twice a week, say...
No idea abou the stripe, though
