Tidal forces earth size bodies that close together would exert on each other would make things rough
Lots of volcanic and seismic activity, not to mention tides might cover continents
Yep, the system in the OP is a lot closer together than our own. So while several of the planets fall within the Goldilocks zone in terms of sunlight they'd experience plenty of tidal forces from their neighbors gravity.

With over 400 active volcanoes, Io is the most geologically active object in the Solar System.[8][9] This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean satellites—Europa, Ganymede and Callisto.
