Gemini monsters are all normal monsters with effects that can be activated by normal summoning them. To use their abilities, you will have to use up your normal summon by selecting the card when they're face up on the field and normal summon them. You can only normal summon 1 monster per turn, if you use that to get a monster to the field then you will have to wait until next turn to do it.
Since all of them are normal monsters at first, you can use Order to Charge to deal with any monster. This will send them to the graveyard, which will only help you later when you have Woodland Arher. Alternatively, you can also use Enemy Controller to tribute your own monster to send them to the graveyard, or use it to protect your monster so you can normal summon it later.
Woodland Archer can be special summoned when you have at least 2 normal monsters, and since all gemini monsters are considered to be normal monsters when in the graveyard, this means that any monster in the graveyard will benefit the archer. The other use for monsters in the graveyard is to revive them by using Blazewing Butterfly to get any gemini monsters back on to the field.
Super Double Summon is a quick-play spell, which allows any gemini monster to have it's ability instantly. It's not recommended to use Super Double Summon during your turn to attack the enemy, since most players often have defensive cards like Windstorm of Etaqua or Sphere Kuriboh. Use this to destroy enemy monster during their turn or use it for Blazewing to revive any gemini monster with it's effects already available.
