Yard Help - Multiple Issues (Pics) - UPDATE

I have several issues going on with my yard and am in need of major help.

Some background: In Oklahoma, house was built in 2016, I bought it in 2018. Pretty sure I have a Bermuda base but now have several different grasses growing. I have an in ground sprinkler system and just turned it back on 2 weeks ago. Have it going about 5 minutes per station right now every other day and we've been getting a lot of rain lately.

I'm a first time homeowner so all of this is new to me and I've already made some mistakes. Last year in trying to get my yard greener I spread some tall fescue seeds on both the front and back yards (I just went to Home Depot online and bought whatever had the best reviews). I signed up for a yearly yard treatment plan - 4 weed & feed treatments and 3 fertilizer treatments (theses spray treatments are a huge thing up here, everyone gets them). I had a weed & feed treatment about a month ago now. The weeds were very bad before they sprayed and they all disappeared, but now I have a few new, different type of weeds popping up so I spread my own Scotts Weed & Feed yesterday.

My only neighbor (I live on a corner lot) could care less about their yard and basically has a clover patch going so I know that's not helping me at all. My house backs up to a huge ag field that the farmer just lets grow up a few times a year so I'm pretty sure I'm getting some seeds in my yard from whatever grass he let's grow up back there.

I'll number the issues to make them easier to refer to.

Front Yard:
1. I all of a sudden have bunches of this grass popping up in the front yard. It grows much quicker than the rest of the yard and is much greener. After some research I'm guessing rye grass? How can I get rid of it? Just pull up each bunch of it or is there something I can treat it with to kill it but not the bermuda base?



2. My front yard is fairly sloped away from the house in all directions. In the corner of the front yard closest to the street my grass is just dying. I have been making sure it gets plenty of water so I know that's not the issue. I think I've seen on this board before that a fungus can do this? Thoughts & suggestions?



3. I have oddly shaped holes popping up in the front yard. The first 2 have been there for a few months now and I just found a 3rd yesterday, it's brand new. The existing holes are just getting worse. Any idea what could be causing these? Sticking my hand down in the holes they are pretty damp. My initial thought was a sprinkler line has busted underground and is causing the ground to saturate, but the lines have been empty until 2 weeks ago. Could it just be the ground settling since the house is still fairly new?



Back Yard:
4. In the back yard I have several different grasses growing. Some of it is the same grass that I have up front, closer to the fence there is another type that is thicker and bigger bunches, the light green in the first and 3rd pictures I think is some tall fescue that took hold, then whatever the 4th picture is. Again, is there anyway to get rid of these grasses without killing the base?





5. Then lastly in the back my yard slopes up to the fence that separates the ag field behind it. On the slope along the entire property line the grass is disappearing and turning up bare spots.



I know it's a lot but thanks in advance for any help provided. Last year I worked out of town all spring and summer so my yard looked like shite and this year I said I was going to get ahead of it and have a beautiful lawn. I thought I was on the right track then it seems like in the last couple weeks it's all gone to shite.
