There are no requirements or restrictions on what clothing a deaconess should wear for Holy Communion. Many churches have their ministers wear white attire for the distribution of Communion.
Yes. You should only receive Communion once a day, but Saturday and Sunday are two separate days, so you can receive Communion at the Saturday vigil mass and the Sunday mass.
Clergy in the Anglican Church wear colours which signify the season. I think Lent is purple and Christmas is white, but don't quote me. There are many seasons of varying length Advent, Easter, Epiphany ,Michaelmas, Trinity and a few more. The prayer book should have all the details.
The baptist church take communion or they call it the "Lord's Supper" in following Jesus' commandment to do it in remembrance of Him. Baptists do not take communion every meeting of the congregation and do not hold any salvation in it but only as a remembrance that without Jesus' shedding of his blood then we miss the nourishment of the spirit and communion with the saints of the Lord. There are some that believe that EVERY time we put anything in our mouths we should remember the Lord and give thanks for His sacrifice, therefore the blessing before each meal.
A priest from our parish said that one must be there at least in time for the Our Father to receive Holy Communion, but, in reality, you probably won't be denied Holy Communion if you arrived after the Our Father. Although you should not really even approach to receive if you are that late. If you have arrived that late, and it is a Sunday, you must either attend another Mass to fulfill your obligation or confess before receiving Holy Communion, as it is a mortal sin to miss a Sunday or Holy Day of Obligation Mass.
When talking about Holy Communion, then yes. If you are talking about a communion as a group, then no.
That depends entirely on how many children are making their first Holy Communion. It should be about the length of a normal Sunday Mass what with singing, and homily, and whatnot. If there are a lot of children, and a lot of family members, it might go much longer.

You may never "take" Holy Communion, you may only "receive" Holy Communion. You should receive Holy Communion as frequently as you can, while you are in a state of grace, and have been fasting. You may not receive Holy Communion more than twice a day, and the second time only if you have been to an entire Mass. If you are not in a state of grace, or are not fasting, or have already received Holy Communion that day, you should never receive.

Ah, Christians aren't sad at Holy Communion, they are reverent, or should be.
The abbreviation for the office of "transitional" deacons (those men studying for the priesthood) is Rev Mr. [Reverend Mister]. Permanent Deacons are not supposed to use the term Rev Mr, but are to be know "Deacon"
