The order of Davening in a Shiva Home

So to begin, the minig is to cover all mirrors in the shiva home as well as all pictures either covered or turned around.

Some however permit leaving pictures of great tzaddikim and Torah sages.

If amongst the avelim is a son of the deceased who is of age to daven for the yarmulke, meaning bar mitzvah, and is able to do so, then he should be leading the prayers for each day of the seven days of shiva as well as throughout the entire eleven months.

This applies for each and every son of the deceased.

And hence, if there's more than one son at the Shiva home, then several minyanim should take place, one for each son, if possible.

In the event that there are no male mourners, or that they are not able to daven for the yambot, so someone else should be delegated to be the chazan.

On certain days, such as Reish Chodesh, the mourners do not daven for the Yomot.

However, on Chanukah Purim, and regular days that Tachnan is omitted, the custom is for the mourner to daven for the Yomot as usual.

It's customary for specifically the Oval who will be leading the prayers, as Chazan, to light five candles during the services of Shachar's Minchan Meirev.

The candles should be placed in front of or near the Chazan.

Even if the Oval is not leading the prayers, such as Reish Chodesh, they should nevertheless be lit by the Oval if the Oval is participating in the minyan.
