it's a wedding ceremony. The chuppah itself is what the bride and groom stand under, but most people call the ceremony itself a chuppah
In general, on the right-hand side of the bride.
The Rabbi reads the Ketubah (wedding vows) as the bride and groom stand under the wedding canopy (Chuppah) in the presence of the guests. Then he says seven blessings over a cup of wine, and the groom places a ring on the bride's finger and ceremoniously declares that he is betrothing her.
The groom stands to the right sideways to watch his bride come down the aisle and his Best Man stands beside him.
* The Bride and Groom sit in the middle of the head table and the bride is on the Groom's right; then her Maid (or Matron) of Honor; then the Bridesmaids. To the left of the Groom is his Best Man and the Ushers.
they stand on the side of their family and where the guests are seated
It is becoming more and more common that the bride and groom welcome the guests to the wedding reception and then they are announced into the reception hall. Usually it is the parents of the bride, or the parents of the bride and groom.
If there is a Ring Bearer (generally a young male child) he will come down the aisle before the bridesmaid and stand by the bride and then she will take the groom's wedding band off the small silk pillow and put it on the groom's finger while saying her vows to him. If there is no Ring Bearer then it is the Maid of Honor that holds the groom's wedding band. The Best Man is the one who will hold the wedding band for the bride and give it to the groom when he is saying his vows to his wife-to-be.
* No, the mother of the bride and the parents of the groom sit in the front pews closest to the bride and groom as the father of the bride will walk down the aisle with his daughter, side down with his wife, then will stand to give his daughter's hand in marriage and sit back down again. The groom and his best man are already standing at the right of the altar.
