Junior Bridesmaids can wear the same colors as your adult bridesmaids. In fact, many designers are offering a junior bridesmaid version of their regualr bridesmaids dresses. One designer, Alexia Designs has a very beautiful selection of junior bridesmaids dresses which match their bridesmaids dresses.
Traditionally, the bridesmaids and junior bridesmaids will go first. The maid of honor will follow the bridesmaids/junior bridesmaids; the maid of honor will be followed by the flower girl.
You can wear whatever color you want, but white is the traditional color and it may be hard to find a wedding dress that isn't white. The grooms always look better in black. Don't let the bridesmaids look better than you.

It depends on what colors you have chosen for your wedding (usually people choose two wedding colors). Since your bridesmaids are wearing red, I will assume that red is one color you have chosen for your wedding. What is the other color? Have your maid of honor wear your other wedding color.Another suggestion is your maid of honor can wear pink.
No, the Maid of Honor or anyone else in the wedding part or any guests should not wear the same color (white) as the bride as she is the focal point (it is her day of glory.) It is fine to wear black and white or another color and white. The Maid of Honor generally wears a slightly different color than the bridesmaids. Example: Bridesmaids are in light blue then the Maid of Honor may be in a midnight blue.
Your wedding, your choice. The bridesmaids can wear whatever color you and your groom decide is OK (assuming, of course, you're paying for the wedding. Parents who are paying tend to want a say in what's done, too.)
depending on how old they are and its all up to the bride
MOBs and MOGs generally wear an outfit that they like, and then corsages are worn by them and the bridesmaids, the corsages matching the men's boutonnieres. The good MOBs and MOGs are careful to not wear colors that clash with the bridesmaids dresses. No one, but NO . . . ONE should dress up and make up in competition to the bride, who should be the "prettiest of them all".
It is suitable for bridesmaids to wear black dresses. While this was previously a color associated with funerals, there is no fashion ruling that it is not appropriate throughout the year for a wedding to include black bridesmaid dresses. It's now become prosaic for bridesmaids to wear black dresses.
the mother of the bride should wear red because it color coordinates well.
