Orbital period in itself is just a number. Interesting variable is how does the climate on planet change during it. On Earth climate gets affected because of axial tilt of the planet, giving different hemisphere different amount of solar energy during a year (due to length of a day and Sun path on the sky).
If those planets have little axial tilt and little variety in distance to their star, there should be little variety in climate on them.
Since it is tidally locked around a low mass star, axial tilt should be near 0 and seasons should not exist [1]. Tidally locked also means much higher temperature than the estimated average (231K or -42C for the hotter one) on the sunny side and much lower ones on the dark side.
There are other ways for a planet to become tidally locked, for example Mercury is in a 3:2 resonance with the Sun. And if there is an atmosphere or a sufficiently deep ocean then even for a 1:1 tidally locked planet the temperature gradient from the light to dark side won't be too extreme.
If those planets have little axial tilt and little variety in distance to their star, there should be little variety in climate on them.
