Branches turning brown and brittle newly transplanted in early summer. Had in a pail of water before planting . How can I help this tree survive
Keep the tree watered so the soil is moist but not saturated. Add mulch to conserve the water, but do not let the mulch touch the tree trunk.
Also, a root stimulator mixed with water per instructions can help the roots grow and reestablish.
I have a 3’ cedar I dug from ground in Blackfoot, Idaho. I want to put in a container but afraid it will freeze or die. First can I plant it in container and second if so, how do I protect the roots in freezing weather. Thanks inadvance
You don't say what kind of cedar but they are typically too large for a container, however I included information on planting in containers. In the winter you can move the container to an unheated garage or shed and water occasionally.

I live in zone 7 and I want one of these trees
This is a type of Deodar Cedar. They are only barely hardy down to zone 7, so you will need to offer quite a bit of winter protection until it is well established.

a month ago I got right in there and cleaned out all the dead cedar leaves from right inside the trees. Then I topped up the soil with peat moss, and have kept them fairly well watered. Now the trees are showing brown dying leaves on the outside, just on so.e tips, but it's fairly uniform. Did I do something wrong? If so, how do I fix?
It looks like very vigorous, new growth. This can appear discolored, but it will return to green.
Likely, this just got a little too much attention all at once. I would recommend giving the shrub slow, steady care throughout the year.
Because this is a Thuja, it will have the same care as its cousins, which are kept tall. This article will help:

I have a ceder tree growing next to my creek. Several actually. I noticed something that looked similar to my "sensitive plant" that I have in my house (which is of the mimosa) I thought maybe a mimosa was growing under or next to it until I looked closer and the branches that had the mimosa like leaves were coming out of the end of the ceder branches!?? I have never seen anything like it. Any ideas?
Unfortunately, your photo did not come through. I am unable to identify the issue in question.
Can you identify the tree in the photos?
That appears to be Cryptomeria japonica, or Japanese Cedar. This article will help:
