Based on the presented stats:
The #1 would be judged as a Mixed Sweeper with its 200 Attack, 220 Special Attack, and 210 Speed stats respectively. But, its lackluster stats of 30 HP and 20 in both defenses respectively render this one to be instantly OHKOed at any given opportunity.
The #2 would be judged as pretty balanced with its 150 in HP, Attack, and both defense stats, making this one a good Physically Offensive Wall. The only thing bad about this one is its 50 in Special Attack and Speed, meaning that it won't be able to outspeed almost anything as well as take any Special hits (unless it knows damage-dealing priority moves).
The #3 would not fair as well as the #2 due to its poor defense stats of 77 and Special Attack stat of 76. This one would also not be a good Specially Offensive Wall, meaning that it would go down quick to almost any attack. On the brighter side, its 200 Speed, 100 HP, and 170 Attack make this one a Bulky Physical Sweeper.
This is how I would judge these based on the presented stats.
Take a look at this if you need any guidance to balance out those stats.
