Low oil, coolant and atf 1995 525i E34

[spacemen12]

Hi,
I had a message two days ago about low coolant level, so I topped it up (about 1qt). Then yesterday I got low oil warning, so I topped it up (about 1/2 qt). Those two messages back to back scared me, so I went under the car to see what is going on. Here are some pics:

I did not lift the car, so those picture are when I crawled under it from the front of the car.

Look like there are some leaks, because it was wet. But I don't know where to look for the oil leak source, because I don't know the oil path under the hood. As for the coolant leak, I can say that it is not from the 2 hoses going out of the radiator to the engine (front of it). I was no able to follow the 3rd hose (lower driver side) to its destination. Can you help me find the source of those leaks.

Also look like the steering atf is leaking near one of the hose...

Otherwise the car drive good. and there is no other symptoms (I am a newbe, so maybe there is an elephant somewhere...)

How much should I expect to pay for all this. Can a newbe (me) do any of those?

Thanks,

P.S. I change a coolant hose (radiator to front engine) about 300mi ago and I did the long procedure to make sure there was not air in the coolant. My mechanics changed my head gasket about 1000mi ago. I had that car for 1300mi and it is 211XXXmi old.

My oil leak was from my oil pressure sensor- I found it accidently. You can do what they used to call the fat chick test. Get a soft bristle brush, soap and water, and clean everything. Make it pretty. Then dust it all with flour after it's nice and dry, and look for the wet spots. Start it up, and look again. Sometimes it's more than one thing ...
