What kind of grass can I plant under my mesquite tree?
These trees tend to grow where other things cannot and they also tend to grow in more arid locations. I am not certain as to your exact conditions, so I will advise based on the typical environment of the mesquite tree.
First, be aware that growing grass under any tree is difficult and growing grass under a tree in conditions that mesquite normally grow it will be very difficult. You may want to look at other groundcovers or alternative solutions.
But, if you are still wanting to try, zoysia or bermuda grass would probably be your best choices. They can take the dry conditions (though you will still need to water regularly) and are often found growing in conditions that are less than ideal for grass.
Several years ago a large branch of an old mesquite in our AZ yard snapped in heavy wind and had to be cut off totally. Since then the "wound" has continued to "bleed", and since that part of the mesquite overhangs a flagstone terrace, the terrace continues to accumulate sticky black pitch. After rains, this splatters even farther. How can the "bleeding" be stopped? How can the accumulation of pitch be cleaned off the flagstone?
It sounds like the tree has slime flux. The jury is out on this disease in terms of how lethal it is. Some people feel that Mesquite can recover from it fine after being infected while others feel that it is potentially dangerous to the long term health of the tree.
There is no known "cure" for slime flux. It is something the tree has to battle itself. But, proper water and nutrients will go a long way to helping it recover.
As for cleaning the sap, this article may help:

I have a very large and very old mesquite tree. I noticed about 2 feet off the ground in an area where the bark must of been damaged years ago, a large dark oozing sap like liquid. I have heard about slime lux. Someone on this site mentioned installing a plastic or iron drain to drain the sap away from the trunk. Could someone explain how to make this or send a photo?
This article should help you with that:

I have several chili mesquite trees that are dripping sap on their trunks. They are young trees, 2-3 yrs. Too much sap! What is causing it? Thank you for helping.
Dripping sap might be caused by some kind of damage to the trunk, or borer insects; or it might be honeydew from one of several insects. These articles have more information: https://www.gardeningknowhow.com/ornamental/trees/tgen/what-is-tree-sap.htm

I have a mature Mesquite tree in Phoenix. In the month of March, most of the tree leaves have turned yellow. Have I watered the tree too much and I stop watering for a period?
The yellowing of leaves on mesquite trees could be caused by improper watering, a nutrient imbalance, or pests and diseases. How much and how often do you water your mesquite tree? Check the soil - is it soggy? If you have over-watered it, then you need to refrain from watering it for a little bit. Have you been fertilizing your tree? Inspect the tree closely - does the tree have any signs of insect damage?

We've received an unusually high amount of rain this spring and I just noticed that most of my mesquite tree's leaves are turning yellow and falling off in very large amounts. I've read that too much water can cause this to happen, but I am very concerned that they will also die from losing too many leaves. Right now about 1/2 the leaves have fallen off, per tree. Should I be concerned or will they survive? Thank you for your time.
Yes, the heavy rains can stress the tree or even worse. Watch for further issues as in the article below.

Can a mesquite tree and a Mexican bird of paradise grow in the same spot? I have two saplings that decided to grow next to each other, a Mesquite tree and a Mexican red bird of paradise. Well, I planted the bird of paradise sapling and then I noticed the Mesiquite pop up about two weeks later. Both are doing very well and I was concerned about them being so close (about 10 inches apart) should I move one and which would be the best one to move?
Yes, I would recommend separating the 2 plants.
They both should be fine to divide as they are still quite small.
Here is links with growing information.
